以下对至少一个示例性实施例的描述实际上仅仅是说明性的,决不作为对本公开及其应用或使用的任何限制。也就是说,本文中的结构及方法是以示例性的方式示出,来说明本公开中的结构和方法的不同实施例。然而,本领域技术人员将会理解,它们仅仅说明可以用来实施的本公开的示例性方式,而不是穷尽的方式。此外,附图不必按比例绘制,一些特征可能被放大以示出具体组件的细节。

在这里示出和讨论的所有示例中,任何具体值应被解释为仅仅是示例性的,而不是作为限制。因此,示例性实施例的其它示例可以具有不同的值。
在分子存储技术中,可以用不同的分子模块来表示待存储的信息中的不同的内容,并通过组装这些分子模块来表示完整的待存储的信息。本公开提出了一种分子模块组装方法和分子模块组装设备,在根据待存储的信息确定了分子模块及其组装顺序后,可以采用基于介电润湿(Electrowetting-on-dielectric,EWOD)效应的数字微流控(Digital Microfluidics,DMF)技术来操纵包含各种分子模块的液滴,使这些液滴沿着期望的路径移动和混合,进而使其中的分子模块按照期望的方式反应和组装,以产生与待存储的信息对应的分子。
在本公开的一示例性实施例中,如图1所示,分子模块组装方法可以包括:
步骤S100,根据待存储的初始信息确定相应的分子模块和组装顺序。
例如,在一具体示例中,对于下面的表1中所示的一段二进制信息,其具有共1010位,且每一位上的内容的取值可以为0或者1。相应地,可以用两种不同的分子模块来分别表示内容0和内容1,并用1010种不同的分子模块来分别表示1010个地址,通过按照预设规则来合成或组合上面所述的(2+1010)种分子模块,可以表示表1中所示的这段信息,如图2中所示的存储形式,其中每个小矩形框表示一种分子模块。
表1
然而,可以理解的是,用于存储信息的由1010量级的不同分子模块所形成的分子模块库将是非常庞大的,其组装难度很高,这会导致将信息写入到分子中变得非常困难。此外,在读取信息时,可能涉及分析鉴别1010量级的不同分子模块,这也是非常困难的。
为了解决上述问题,可以通过对待存储的初始信息进行重编码来大幅度地减少所需的分子模块的种数,以方便组装。在一些实施例中,如图3所示,步骤S100可以包括:
步骤S110,获取待存储的初始信息,并用第一地址编码和第一内容编码来表示初始信息。
其中,初始信息可以包括各种形式的信息,例如文字信息、图片信息、音频信息或视频信息等。在信息技术中,可以方便地将上述各种形式的信息转换为例如二进制编码等。在后文中,将以初始信息为二进制编码的信息为例,详细阐述本公开的技术方案。然而可以理解的是,根据需要,初始信息也可以是其他进制编码的信息。
进一步地,可以用第一地址编码和第一内容编码来表示获取到的初始信息,其中,初始信息中的每个位置可以分别由与该位置一一对应的第一地址编码来表示,且初始信息的每个位置处的内容可以分别由相应的第一内容编码来表示。
在一些实施例中,获取待存储的初始信息,并用第一地址编码和第一内容编码来表示初始信息可以包括:
获取初始信息;
确定初始信息中的与一个第一地址编码对应的一个位置处的内容的单位位数;
当初始信息的总位数是单位位数的整数倍时,将初始信息划分为一个或多个初始信息片段;
当初始信息的总位数不是单位位数的整数倍时,对初始信息进行补位,使所得的补位初始信息的总位数是单位位数的整数倍,并将补位初始信息划分为一个或多个初始信息片段。
其中,在初始信息中的每个位置处的内容的单位位数彼此相等,且每个初始信息片段的位数为单位位数。也就是说,在用第一地址编码和第一内容编码来表示初始信息时,将初始信息划分为各自具有单位位数的一个或多个初始信息片段,并赋予每个初始信息片段相应的第一地址编码和第一内容编码,以便后续的处理。
当初始信息的总位数不是单位位数的整数倍时,可以在初始信息中补充占位内容, 其中,初始信息中的占位内容与非占位内容可以分别对应于不同的分子模块。具体而言,可以在初始信息的头部、尾部和中间的一处或多处补充占位内容(在一些实施例中,该占位内容可以用“0”来表示,但要注意的是,用于补位的“0”和初始信息中原有的“0”是不同的,相应地也要用不同的分子模块来表示这两种不同的“0”,在本文中,以下划线标出作为占位内容的“0”)。由于初始信息中的占位内容与非占位内容分别对应于不同的分子模块,因此在读取信息时可以方便地进行区分。例如,如果初始信息为“1001100010110001”,单位位数为3,即初始信息的总位数16不是单位位数3的整数倍时,那么可以在初始信息的头部补充占位内容,所得的补位初始信息为“001001100010110001”。或者,可以在初始信息的尾部补充占位内容,所得的补位初始信息可以被表示为“100110001011000100”。此外,可以理解的是,在一些实施例中,当可以采用其他方式来区分占位内容与非占位内容时(例如,可以将位于信息的头部的一个或多个“0”直接视为占位内容),也可以用相同的分子模块来表示占位内容和非占位内容。
单位位数,或者说对初始信息的不同划分方式可以是根据需要来确定的。例如,对于初始信息“1001100010110001”,可以将其划分为如下面的表2至表8中所示的不同的初始信息片段:
表2
在表2所示的具体示例中,初始信息片段的单位位数为1。第一地址编码可以包括“0”、“1”、“2”、“3”、“4”、“5”、“6”、“7”、“8”、“9”、“10”、“11”、“12”、“13”、“14”和“15”共16种,而第一内容编码可以包括“0”和“1”共2种。
表3
在表3所示的具体示例中,初始信息片段的单位位数为2。第一地址编码可以包括“0”、“1”、“2”、“3”、“4”、“5”、“6”和“7”共8种,而第一内容编码可以包括“00”、“01”、“10”和“11”共4种。
表4
表5
在表4和表5所示的具体示例中,初始信息片段的单位位数为3。由于初始信息的总位数不是单位位数的整数倍,在表4中,在初始信息的头部补充了作为占位内容的两个“0”,以使所得的补位初始信息的总位数是单位位数的整数倍,以便于划分。第一地址编码可以包括“0”、“1”、“2”、“3”、“4”和“5”共6种,而相应的第一内容编码可以包括“001”、“010”、“100”和“110”共4种。此外,当以这种方式来表示其他具体的初始信息时,第一内容编码还可能包括“000”、“011”、“101”和“111”中的一种或多种。
另外,如表5中所示,可以通过在初始信息的尾部补充占位内容来使补位初始信息的总位数是单位位数的整数倍。需要注意的是,这里用“0”表示了占位内容,但也可以用其它字符来表示,且用于占位的“0”和初始信息中的其它“0”具有不同的含义,在后续步骤中,可以用不同的分子模块来分别表示。
表6
在表6所示的具体示例中,初始信息片段的单位位数为4。第一地址编码可以包括“0”、“1”、“2”和“3”共4种,而相应的第一内容编码可以包括“1001”、“1000”、“1011”和“0001”。可以理解的是,在其它具体示例中,第一内容编码也可能是其它的四位二进制数,这里不再枚举。
表7
在表7所示的具体示例中,初始信息片段的单位位数为8。第一地址编码可以包括“0”和“1”共2种,而相应的第一内容编码可以包括“10011000”和“10110001”。可以理解的是,在其它具体示例中,第一内容编码也可能是其它的八位二进制数,这里不再枚举。
表8
在表8所示的具体示例中,初始信息片段的单位位数为16。第一地址编码可以包括“0” 共1种,而相应的第一内容编码可以包括“1001100010110001”。可以理解的是,在其它具体示例中,第一内容编码也可能是其它的十六位二进制数,这里不再枚举。
此外,第一地址编码和第一内容编码也可以被转换为其它进制,八进制、十进制、十六进制等。
返回图3,步骤S100还可以包括:
步骤S121,分别对每个第一地址编码进行重编码,以用具有第一预设位数和第一预设进制的第一重编码信息来表示相应的一个第一地址编码;
步骤S131,根据第一内容编码和第一重编码信息来确定相应的分子模块和组装顺序。
在一些实施例中,第一预设位数B1与第一预设进制S1的和(B1+S1)可以小于第一地址编码的不同取值的最大可能种数,以有效地减小表征第一地址编码所需的分子模块的总数目。并且,第一预设进制的第一预设位数次幂(S1B1)可以大于初始信息的第一地址编码的不同取值的最大可能种数,从而使得第一重编码信息能够表示所有可能出现的第一地址编码,以保障编码的可靠性。
例如,利用3位2进制的第一重编码信息,可以用5(即,3+2)个不同的分子模块来表示共8(即,23)个不同的第一地址编码;利用4位2进制的第一重编码信息,可以用6(即,4+2)个不同的分子模块来表示共16(即,24)个不同的第一地址编码;利用5位2进制的第一重编码信息,可以用7(即,5+2)个不同的分子模块来表示共32(即,25)个不同的第一地址编码;利用5位3进制的第一重编码信息,可以用8(即,5+3)个不同的分子模块来表示共243(即,35)个不同的第一地址编码;利用10位10进制的第一重编码信息,可以用20(即,10+10)个不同的分子模块来表示共1010个不同的第一地址编码。由此可见,通过重编码,当需要表示的第一地址编码的数目发生指数增长时,只需要线性增加分子模块的数量即可,因而大幅地压缩了所需的分子模块的种类。
进一步地,可以基于第一内容编码和第一重编码信息来确定相应的分子模块和组装顺序。具体而言,可以分别为第一内容编码和第一重编码信息确定不同的分子模块。
在一些实施例中,在为第一重编码信息确定相应的分子模块时,可以分别为第一重编码信息中的不同位上的内容确定不同的分子模块,并且分别为第一重编码信息中的同一位上的不同内容确定不同的分子模块。需要注意的是,在这样的实施例中,对于第一重编码信息中的在不同位置上的相同内容,也会用不同的分子模块来表示,以将位置信息包含在分子模块中,从而区分位于不同位置上的相同内容。
例如,在一具体示例中,当所获取的初始信息为“10011000”时,可以按照上文所述 的方式将其表示为如下面的表9中所示的形式:
表9
进一步地,可以将其中的每个第一地址编码重编码为3位2进制的第一重编码信息,如下面的表10所示:
表10
相应地,可以分别用分子模块A1和分子模块A2来表示两种不同的第一内容编码“0”和“1”,分别用分子模块B1和分子模块B2来表示第一重编码信息中的第一位上的“0”和“1”,分别用分子模块B3和分子模块B4来表示第一重编码信息中的第二位上的“0”和“1”,并分别用分子模块B5和分子模块B6来表示第一重编码信息中的第三位上的“0”和“1”,其中,分子模块A1、分子模块A2、分子模块B1、分子模块B2、分子模块B3、分子模块B4、分子模块B5和分子模块B6为分子或分子片段,且它们两两各不相同。这样,共需要8种不同的分子模块来表示8位2进制的初始信息。可以看到,虽然分子模块B1、B3和B5都表示“0”,但由于其表示第一重编码信息中的不同位置上的“0”,因此它们是彼此不同的,以区分不同位置上的“0”。类似地,表示不同位置上的“1”的分子模块B2、B4和B6也是彼此不同的。
在一具体示例中,组合后所得的存储形式可以如图4中所示。其中,以第一行为例,从左往右的第一个至第四个分子模块分别表示初始信息的第一位“1”的第一内容编码、第一地址编码的第一重编码信息中的第一位上的“0”、第一地址编码的第一重编码信息中的第二位上的“0”和第一地址编码的第一重编码信息中的第三位上的“0”。以此类推,第一行中的第一条链对应于初始信息“10011000”中的第1位“1”,第二行中的第二条链对应于初始信息“10011000”中的第2位“0”,第三行中的第三条链对应于初始信息“10011000”中的第3位“0”,第四行中的第四条链对应于初始信息“10011000”中的第4位“1”,第五行中的第五条链对应于初始信息“10011000”中的第5位“1”,第六行中的第六条链对应于初始信息“10011000”中的第6位“0”,第七行中的第七条链对应于初始信息“10011000”中的第7位“0”,第八行中的第八条链对应于初始信息“10011000”中的第8位“0”。每行中的每类分子链可以被混合在一起,或者也可以首尾相连形成更长的分子链来表示初始信息。
在另一些实施例中,步骤S131可以包括:
对于每个第一重编码信息,用第二地址编码和第二内容编码来表示该第一重编码信息,其中,第一重编码信息中的每个位置可以分别由与该位置一一对应的第二地址编码来表示,且第一重编码信息中的每个位置处的内容可以分别由相应的第二内容编码来表示;以及
根据第一内容编码、第二地址编码和第二内容编码来确定相应的分子模块。
如同上文所述的具体示例,当所获取的初始信息为“10011000”时,可以用第二地址编码和第二内容编码来分别表示每个第一重编码信息,如下面的表11所示:
表11
其中,第一内容编码具有“0”和“1”两种不同的取值,第二地址编码具有“0”、“1”和“2”三种不同的取值,而第二内容编码具有“0”和“1”两种不同的取值。
进一步地,在一些实施例中,可以分别为第一内容编码、第二地址编码和第二内容编码确定不同的分子模块,以区分这三种编码。
例如,根据第一内容编码、第二地址编码和第二内容编码来确定相应的分子模块可以包括:
分别为不同取值的第一内容编码确定不同的分子模块;或
分别为不同取值的第二地址编码确定不同的分子模块;或
分别为不同取值的第二内容编码确定不同的分子模块。
例如,在上面表11所示的具体示例中,可以分别用分子模块A1和分子模块A2来表示两种不同的第一内容编码“0”和“1”,用分子模块A3和分子模块A4来表示两种不同的第二内 容编码“0”和“1”,并用分子模块A5、分子模块A6和分子模块A7来表示三种不同的第二地址编码“0”、“1”和“2”,其中,分子模块A1、分子模块A2、分子模块A3、分子模块A4、分子模块A5、分子模块A6和分子模块A7为分子或分子片段,且它们两两各不相同。这样,共需要7种不同的分子模块来表示8位2进制的初始信息。
在本公开的另一具体示例中,组合后所得的存储形式可以如图5中所示。其中,以第一行为例,从左往右的第一个至第七个分子模块分别表示初始信息的第一位“1”的第一内容编码、第一位“1”的第一位第二内容编码“0”和对应的第一位第二地址编码“0”、第一位的第二位第二内容编码“0”和对应的第二位第二地址编码“1”、第一位的第三位第二内容编码“0”和对应的第三位第二地址编码“2”。以此类推,第一行中的第一条链对应于初始信息“10011000”中的第1位“1”,第二行中的第二条链对应于初始信息“10011000”中的第2位“0”,第三行中的第三条链对应于初始信息“10011000”中的第3位“0”,第四行中的第四条链对应于初始信息“10011000”中的第4位“1”,第五行中的第五条链对应于初始信息“10011000”中的第5位“1”,第六行中的第六条链对应于初始信息“10011000”中的第6位“0”,第七行中的第七条链对应于初始信息“10011000”中的第7位“0”,第八行中的第八条链对应于初始信息“10011000”中的第8位“0”。每行中的每类分子链可以被混合在一起,或者也可以首尾相连形成更长的分子链以表示初始信息。
或者,根据第一内容编码、第二地址编码和第二内容编码来确定相应的分子模块和组装顺序可以包括:
当第一内容编码具有Nc1种不同取值时,分别为(Nc1-1)种不同取值的第一内容编码确定不同的分子模块,并使剩余的一种取值的第一内容编码不对应于任何分子模块;或
当第二地址编码具有Na2种不同取值时,分别为(Na2-1)种不同取值的第二地址编码确定不同的分子模块,并使剩余的一种取值的第二地址编码不对应于任何分子模块;或
当第二内容编码具有Nc2种不同取值时,分别为(Nc2-1)种不同取值的第二内容编码确定不同的分子模块,并使剩余的一种取值的第二内容编码不对应于任何分子模块。
也就是说,某一取值的一种编码可以不对应于任何分子模块,而是用缺失状态来表示,这可以减少所需的分子模块的不同种类的数目。
例如,在上面表11所示的具体示例中,可以用分子模块A1来表示第一内容编码“0”,而用缺失状态来表示第一内容编码“1”,即没有任何分子模块来表示第一内容编码“1”。此外,可以类似地用分子模块A3和分子模块A4来表示两种不同取值的第二内容编码“0”和“1”,并用分子模块A5、分子模块A6和分子模块A7来表示三种不同取值的第二地址编码“0”、“1” 和“2”,其中,分子模块A1、分子模块A3、分子模块A4、分子模块A5、分子模块A6和分子模块A7为分子或分子片段,且它们两两各不相同。这样,共需要6种不同的分子模块来表示8位2进制的初始信息。
在一些实施例中,也可以分别为第一内容编码、第二地址编码和第二内容编码中的两种编码的不同取值的组合确定不同的分子模块。
在一具体示例中,根据第一内容编码、第二地址编码和第二内容编码来确定相应的分子模块可以包括:
分别为第二地址编码和第二内容编码的不同取值的组合确定不同的分子模块。
例如,在上面表11所示的具体示例中,可以用分子模块A8来表示第二内容编码为“0”且第二地址编码为“0”的组合,用分子模块A9来表示第二内容编码为“0”且第二地址编码为“1”的组合,用分子模块A10来表示第二内容编码为“0”且第二地址编码为“2”的组合,用分子模块A11来表示第二内容编码为“1”且第二地址编码为“0”的组合,用分子模块A12来表示第二内容编码为“1”且第二地址编码为“1”的组合,以及用分子模块A13来表示第二内容编码为“1”且第二地址编码为“2”的组合。结合表示第一内容编码的分子模块A1和分子模块A2,也可以完整地表示表11中的初始信息。这样,共需要8种不同的分子模块来表示8位2进制的初始信息。
可以理解的是,也可以分别为第一地址编码和第二地址编码的不同取值的组合确定不同的分子模块,并结合表示第二内容编码的分子模块来表示初始信息;或者也可以分别为第一地址编码和第二内容编码的不同取值的组合确定不同的分子模块,并结合表示第二地址编码的分子模块来表示初始信息。
类似地,可以用缺失状态来表示第一内容编码、第二地址编码和第二内容编码中的一种两编码组合的一种取值。例如,根据第一内容编码、第二地址编码和第二内容编码来确定相应的分子模块可以包括:
当第二地址编码和第二内容编码的组合具有Nac2种不同取值时,分别为(Nac2-1)种第二地址编码和第二内容编码的不同取值的组合确定不同的分子模块,并使剩余的一种取值的第二地址编码和第二内容编码的组合不对应于任何分子模块。
例如,在上面表11所示的具体示例中,可以用缺失状态来表示第二内容编码为“0”且第二地址编码为“0”的组合,用分子模块A9来表示第二内容编码为“0”且第二地址编码为“1”的组合,用分子模块A10来表示第二内容编码为“0”且第二地址编码为“2”的组合,用分子模块A11来表示第二内容编码为“1”且第二地址编码为“0”的组合,用分子模块A12来表示第二 内容编码为“1”且第二地址编码为“1”的组合,以及用分子模块A13来表示第二内容编码为“1”且第二地址编码为“2”的组合。结合表示第一内容编码的分子模块A1和分子模块A2,也可以完整地表示表11中的初始信息。这样,共需要7种不同的分子模块来表示8位2进制的初始信息。
如图6所示,在本公开的另一示例性实施例中,也可以对第一内容编码进行重编码。具体而言,步骤S100可以包括:
步骤S122,分别对每个第一内容编码进行重编码,以用具有第二预设位数和第二预设进制的第二重编码信息来表示相应的一个第一内容编码;以及
步骤S132,根据第一地址编码和第二重编码信息来确定相应的分子模块和组装顺序。
在一些实施例中,第二预设位数B2与第二预设进制S2的和(B2+S2)可以小于第一内容编码的不同取值的最大可能种数,以有效地减小表征第一内容编码所需的分子模块的总数目。并且,第二预设进制的第二预设位数次幂(S2B2)可以大于第一内容编码的不同取值的最大可能种数,从而使得第二重编码信息能够表示所有可能出现的第一内容编码,以保障编码的可靠性。例如在初始信息片段的单位位数较大的情况下,如果直接遍历所有不同取值的第一内容编码来选取相应的分子模块,则用来表示第一内容编码所需的分子模块的数目较大,因此可以对第一内容编码进行重编码以获得第二重编码信息,以减小用来表示第一内容编码所需的数目。
例如,利用3位2进制的第二重编码信息,可以用5(即,3+2)个不同的分子模块来表示共8(即,23)个不同的第一内容编码;利用4位2进制的第二重编码信息,可以用6(即,4+2)个不同的分子模块来表示共16(即,24)个不同的第一内容编码;利用5位2进制的第二重编码信息,可以用7(即,5+2)个不同的分子模块来表示共32(即,25)个不同的第一内容编码;利用5位3进制的第二重编码信息,可以用8(即,5+3)个不同的分子模块来表示共243(即,35)个不同的第一内容编码;利用10位10进制的第二重编码信息,可以用20(即,10+10)个不同的分子模块来表示共1010个不同的第一内容编码。由此可见,通过重编码,当需要表示的第一内容编码的数目发生指数增长时,只需要线性增加分子模块的数量即可,因而大幅地压缩了所需的分子模块的种类。
进一步地,可以基于第一地址编码和第二重编码信息来确定相应的分子模块。具体而言,可以分别为第一地址编码和第二重编码信息确定不同的分子模块。
在一些实施例中,在为第二重编码信息确定相应的分子模块时,可以分别为第二重编码信息中的不同位上的内容确定不同的分子模块,并且分别为第二重编码信息中的同一 位上的不同内容确定不同的分子模块。需要注意的是,在这样的实施例中,对于第二重编码信息中的在不同位置上的相同内容,将会用不同的分子模块来表示,以将位置信息包含在分子模块中,从而区分位于不同位置上的相同内容。
在另一些实施例中,根据第一地址编码和第二重编码信息来确定相应的分子模块和组装顺序可以包括:
对于每个第二重编码信息,用第三地址编码和第三内容编码来表示该第二重编码信息,其中,第二重编码信息中的每个位置可以分别由与该位置一一对应的第三地址编码来表示,且第二重编码信息中的每个位置处的内容可以分别由相应的第三内容编码来表示;以及
根据第一地址编码、第三地址编码和第三内容编码来确定相应的分子模块。
例如,当所获取的初始信息为“10011000”时,可以按照上文所述的方式将其表示为如下面的表12中所示的形式:
表12
进一步地,可以将其中的每个第一内容编码重编码,并用第三地址编码和第三内容编码来表示,如下面的表13所示:
表13
其中,第三地址编码具有“0”和“1”两种不同的取值,第三内容编码具有“0”和“1”两种不同的取值,且第一地址编码具有“0”、“1”、“2”和“3”共四种不同的取值。
进一步地,在一些实施例中,可以分别为第一地址编码、第三地址编码和第三内容编码确定不同的分子模块,以区分这三种编码。
其中,根据第一地址编码、第三地址编码和第三内容编码来确定相应的分子模块可以包括:
分别为不同取值的第一地址编码确定不同的分子模块;或
分别为不同取值的第三地址编码确定不同的分子模块;或
分别为不同取值的第三内容编码确定不同的分子模块。
例如,在上面表13所示的具体示例中,可以分别用分子模块A14、分子模块A15、分子模块A16和分子模块A17来表示四种不同的第一地址编码“0”、“1”、“2”和“3”,用分子模块A18和分子模块A19来表示两种不同的第三内容编码“0”和“1”,并用分子模块A20和分子模块A21来表示两种不同的第三地址编码“0”和“1”,其中,分子模块A14、分子模块A15、分子模块A16、分子模块A17、分子模块A18、分子模块A19、分子模块A20和分子模块A21为分子或分子片段,且它们两两各不相同。这样,共需要8种不同的分子模块来表示8位2进制的初始信息。
或者,根据第一地址编码、第三地址编码和第三内容编码来确定相应的分子模块可以包括:
当第一地址编码具有Na1种不同取值时,分别为(Na1-1)种不同取值的第一地址编码确定不同的分子模块,并使剩余的一种取值的第一地址编码不对应于任何分子模块;或
当第三地址编码具有Na3种不同取值时,分别为(Na3-1)种不同取值的第三地址编码确定不同的分子模块,并使剩余的一种取值的第三地址编码不对应于任何分子模块;或
当第三内容编码具有Nc3种不同取值时,分别为(Nc3-1)种不同取值的第三内容编码确定不同的分子模块,并使剩余的一种取值的第三内容编码不对应于任何分子模块。
也就是说,某一取值的一种编码可以不对应于任何分子模块,而是用缺失状态来表示,这可以减少所需的分子模块的不同种类的数目。
例如,在上面表13所示的具体示例中,可以用缺失状态来表示第一地址编码“0”,即没有任何分子模块对应于第一地址编码“0”,并分别用分子模块A15、分子模块A16和分子模块A17来表示其它三种不同的第一地址编码“1”、“2”和“3”。此外,可以类似地用分子模块A18和分子模块A19来表示两种不同的第三内容编码“0”和“1”,并用分子模块A20和分子模块A21来表示两种不同的第三地址编码“0”和“1”,其中,分子模块A15、分子模块A16、分子模块A17、分子模块A18、分子模块A19、分子模块A20和分子模块A21为分子或分子片段,且它们两两各不相同。这样,共需要7种不同的分子模块来表示8位2进制的初始信息。
在一些实施例中,也可以分别为第一地址编码、第三地址编码和第三内容编码中的两种编码的不同取值的组合确定不同的分子模块。
在一具体示例中,根据第一地址编码、第三地址编码和第三内容编码来确定相应的分子模块和组装顺序可以包括:
分别为第三地址编码和第三内容编码的不同取值的组合确定不同的分子模块。
例如,在上面表13所示的具体示例中,可以用分子模块A22来表示第三内容编码为“0”且第三地址编码为“0”的组合,用分子模块A23来表示第三内容编码为“0”且第三地址编码为“1”的组合,用分子模块A24来表示第三内容编码为“1”且第三地址编码为“0”的组合,用分子模块A25来表示第三内容编码为“1”且第三地址编码为“1”的组合。结合表示第一地址编码的分子模块A14、分子模块A15、分子模块A16和分子模块A17,也可以完整地表示表13中的初始信息。这样,共需要8种不同的分子模块来表示8位2进制的初始信息。
可以理解的是,也可以分别为第一地址编码和第三地址编码的不同取值的组合确定不同的分子模块,并结合表示第三内容编码的分子模块来表示初始信息;或者也可以分别为第一地址编码和第三内容编码的不同取值的组合确定不同的分子模块,并结合表示第三地址编码的分子模块来表示初始信息。
类似地,可以用缺失状态来表示第一地址编码、第三地址编码和第三内容编码中的一种两编码组合的一种取值。例如,根据第一地址编码、第三地址编码和第三内容编码来确定相应的分子模块可以包括:
当第三地址编码和第三内容编码的组合具有Nac3种不同取值时,分别为(Nac3-1)种第三地址编码和第三内容编码的不同取值的组合确定不同的分子模块,并使剩余的一种取值的第三地址编码和第三内容编码的组合不对应于任何分子模块。
例如,在上面表13所示的具体示例中,可以用缺失状态来表示第三内容编码为“0”且第三地址编码为“0”的组合,用分子模块A23来表示第三内容编码为“0”且第三地址编码为“1”的组合,用分子模块A24来表示第三内容编码为“1”且第三地址编码为“0”的组合,用分子模块A25来表示第三内容编码为“1”且第三地址编码为“1”的组合。结合表示第一地址编码的分子模块A14、分子模块A15、分子模块A16和分子模块A17,也可以完整地表示表13中的初始信息。这样,共需要7种不同的分子模块来表示8位2进制的初始信息。
在本公开的又一示例性实施例中,也可以对第一地址编码和第一内容编码两者都进行重编码。具体而言,如图7所示,步骤S100可以包括:
步骤S123,分别对每个第一地址编码和每个第一内容编码进行重编码,以用具有第一预设位数和第一预设进制的第一重编码信息来表示相应的一个第一地址编码,并用具有第二预设位数和第二预设进制的第二重编码信息来表示相应的一个第一内容编码;
步骤S133,根据第一重编码信息和第二重编码信息来确定相应的分子模块和组装顺序。
如上文所描述的,在一些实施例中,第一预设位数与第一预设进制的和(B1+S1)可 以小于第一地址编码的不同取值的最大可能种数,以及第二预设位数与第二预设进制的和(B2+S2)可以小于第一内容编码的不同取值的最大可能种数,以有效地减小表征第一地址编码和第一内容编码所需的分子模块的总数目。此外,第一预设进制的第一预设位数次幂(S1B1)可以大于第一地址编码的不同取值的最大可能种数,以及第二预设进制的第二预设位数次幂(S2B2)可以大于第一内容编码的不同取值的最大可能种数,从而使第一重编码信息和第二重编码信息能够分别表示所有可能出现的第一地址编码和第一内容编码,以保障编码的可靠性。
在一些实施例中,根据第一重编码信息和第二重编码信息来确定相应的分子模块可以包括:
分别为第一重编码信息和第二重编码信息确定不同的分子模块。
如上文所述的,在一些实施例中,可以分别为第一重编码信息中的不同位上的内容确定不同的分子模块,并且分别为第一重编码信息中的同一位上的不同内容确定不同的分子模块。
类似地,在一些实施例中,可以分别为第二重编码信息中的不同位上的内容确定不同的分子模块,并且分别为第二重编码信息中的同一位上的不同内容确定不同的分子模块,如上文所述。
在一些实施例中,也可以进一步用第二地址编码和第二内容编码来表示第一重编码信息,其中,第一重编码信息中的每个位置可以分别由与该位置一一对应的第二地址编码来表示,且第一重编码信息中的每个位置处的内容可以分别由相应的第二内容编码来表示,如上文所述。
类似地,在一些实施例中,可以进一步用第三地址编码和第三内容编码来表示第二重编码信息,其中,第二重编码信息中的每个位置可以分别由与该位置一一对应的第三地址编码来表示,且第二重编码信息中的每个位置处的内容可以分别由相应的第三内容编码来表示,如上文所述。
可以理解的是,在一具体示例中,可以分别为第一重编码信息中的不同位上的内容确定不同的分子模块,且分别为第一重编码信息中的同一位上的不同内容确定不同的分子模块,并且分别为第二重编码信息中的不同位上的内容确定不同的分子模块,且分别为第二重编码信息中的同一位上的不同内容确定不同的分子模块。此外,分别与第一重编码信息和第二重编码信息对应的分子模块可以为不同的分子或分子片段。
在另一具体示例中,可以分别为第一重编码信息中的不同位上的内容确定不同的分 子模块,且分别为第一重编码信息中的同一位上的不同内容确定不同的分子模块,并且对于每个第二重编码信息,可以用第三地址编码和第三内容编码来表示该第二重编码信息,且根据第三地址编码和第三内容编码来确定相应的分子模块。此外,分别与第一重编码信息、第三地址编码和第三内容编码对应的分子模块可以为不同的分子或分子片段。
在又一具体示例中,对于每个第一重编码信息,可以用第二地址编码和第二内容编码来表示该第一重编码信息,且根据第二地址编码和第二内容编码来确定相应的分子模块,并且分别为第二重编码信息中的不同位上的内容确定不同的分子模块,且分别为第二重编码信息中的同一位上的不同内容确定不同的分子模块。此外,分别与第二地址编码、第二内容编码和第二重编码信息对应的分子模块可以为不同的分子或分子片段。
在再一具体示例中,对于每个第一重编码信息,可以用第二地址编码和第二内容编码来表示该第一重编码信息,且根据第二地址编码和第二内容编码来确定相应的分子模块,并且对于每个第二重编码信息,可以用第三地址编码和第三内容编码来表示该第二重编码信息,且根据第三地址编码和第三内容编码来确定相应的分子模块。
例如,当所获取的初始信息为“10011000”时,可以按照上文所述的方式将其表示为如表12中所示的形式。进一步地,可以将其中的每个第一地址编码和每个第一内容编码重编码,并用第二地址编码和第二内容编码来表示第一重编码信息,用第三地址编码和第三内容编码来表示第二重编码信息,如下面的表14中所示:
表14
其中,第二内容编码、第二地址编码、第三内容编码和第三地址编码各自具有“0”和“1”两种不同的取值。
进一步地,可以分别为第二地址编码、第二内容编码、第三地址编码和第三内容编码确定不同的分子模块,以区分这些编码。
在一些实施例中,根据第一重编码信息和第二重编码信息来确定相应的分子模块可以包括:
分别为不同取值的第二地址编码确定不同的分子模块;或
分别为不同取值的第二内容编码确定不同的分子模块;或
分别为不同取值的第三地址编码确定不同的分子模块;或
分别为不同取值的第三内容编码确定不同的分子模块。
例如,在上面表14所示的具体示例中,可以分别用分子模块A5和分子模块A6来表示两种不同的第二地址编码“0”和“1”,用分子模块A3和分子模块A4来表示两种不同的第二内容编码“0”和“1”,用分子模块A20和分子模块A21表示两种不同的第三地址编码“0”和“1”,并用分子模块A18和分子模块A19来表示两种不同的第三内容编码“0”和“1”,其中,分子模块A5、分子模块A6、分子模块A3、分子模块A4、分子模块A20、分子模块A21、分子模块A18和分子模块A19为分子或分子片段,且它们两两各不相同。这样,共需要8种不同的分子模块来表示8位2进制的初始信息。
或者,根据第一重编码信息和第二重编码信息来确定相应的分子模块可以包括:
当第二地址编码具有Na2种不同取值时,分别为(Na2-1)种不同取值的第二地址编码确定不同的分子模块,并使剩余的一种取值的第二地址编码不对应于任何分子模块;或
当第二内容编码具有Nc2种不同取值时,分别为(Nc2-1)种不同取值的第二内容编码确定不同的分子模块,并使剩余的一种取值的第二内容编码不对应于任何分子模块;或
当第三地址编码具有Na3种不同取值时,分别为(Na3-1)种不同取值的第三地址编码确定不同的分子模块,并使剩余的一种取值的第三地址编码不对应于任何分子模块;或
当第三内容编码具有Nc3种不同取值时,分别为(Nc3-1)种不同取值的第三内容编码确定不同的分子模块,并使剩余的一种取值的第三内容编码不对应于任何分子模块。
也就是说,一种编码的一种取值可以不对应于任何分子模块,而是用缺失状态来表示,这可以减少所需的分子模块的种类数目。
例如,在上面表14所示的具体示例中,可以用缺失状态来表示第二地址编码“0”,即没有任何分子模块对应于第二地址编码“0”,并用分子模块A6来表示第二地址编码“1”,用分子模块A3和分子模块A4来表示两种不同的第二内容编码“0”和“1”,用分子模块A20和分子模块A21表示两种不同的第三地址编码“0”和“1”,用分子模块A18和分子模块A19来表示两种不同的第三内容编码“0”和“1”,其中,分子模块A6、分子模块A3、分子模块A4、分子模块A20、分子模块A21、分子模块A18和分子模块A19为分子或分子片段,且它们两两各不相同。这样,共需要7种不同的分子模块来表示8位2进制的初始信息。
在一些实施例中,也可以分别为第二地址编码、第二内容编码、第三地址编码和第 三内容编码中的两种编码或三种编码的不同取值的组合确定不同的分子模块。
在一具体示例中,根据第一重编码信息和第二重编码信息来确定相应的分子模块和组装顺序可以包括:
分别为第二地址编码和第二内容编码的不同取值的组合确定不同的分子模块;或
分别为第三地址编码和第三内容编码的不同取值的组合确定不同的分子模块。
例如,在上面表14所示的具体示例中,可以用分子模块A8来表示第二内容编码为“0”且第二地址编码为“0”的组合,用分子模块A9来表示第二内容编码为“0”且第二地址编码为“1”的组合,用分子模块A11来表示第二内容编码为“1”且第二地址编码为“0”的组合,用分子模块A12来表示第二内容编码为“1”且第二地址编码为“1”的组合。此外,还可以用分子模块A22来表示第三内容编码为“0”且第三地址编码为“0”的组合,用分子模块A23来表示第三内容编码为“0”且第三地址编码为“1”的组合,用分子模块A24来表示第三内容编码为“1”且第三地址编码为“0”的组合,用分子模块A25来表示第三内容编码为“1”且第三地址编码为“1”的组合。
在一些实施例中,可以用分子模块A8、分子模块A9、分子模块A10、分子模块A11、分子模块A22、分子模块A23、分子模块A24和分子模块A25来表示8位2进制的初始信息。或者,可以用分子模块A8、分子模块A9、分子模块A10、分子模块A11、分子模块A20、分子模块A21、分子模块A18和分子模块A19来表示8位2进制的初始信息。又或者,可以用分子模块A3、分子模块A4、分子模块A5、分子模块A6、分子模块A22、分子模块A23、分子模块A24和分子模块A25来表示8位2进制的初始信息。
可以理解的是,也可以基于第二地址编码、第二内容编码、第三地址编码和第三内容编码中的其它两种或三种编码的组合来确定相应的分子模块,在此不再赘述。
类似地,可以用缺失状态来表示第二地址编码、第二内容编码、第三地址编码和第三内容编码中的一种组合的一种取值。在一具体示例中,根据第一重编码信息和第二重编码信息来确定相应的分子模块可以包括:
当第二地址编码和第二内容编码的组合具有Nac2种不同取值时,分别为(Nac2-1)种第二地址编码和第二内容编码的不同取值的组合确定不同的分子模块,并使剩余的一种取值的第二地址编码和第二内容编码的组合不对应于任何分子模块;或
当第三地址编码和第三内容编码的组合具有Nac3种不同取值时,分别为(Nac3-1)种第三地址编码和第三内容编码的不同取值的组合确定不同的分子模块,并使剩余的一种取值的第三地址编码和第三内容编码的组合不对应于任何分子模块。
例如,在上面表14所示的具体示例中,可以用缺失状态来表示第三内容编码为“0”且第三地址编码为“0”的组合,用分子模块A23来表示第三内容编码为“0”且第三地址编码为“1”的组合,用分子模块A24来表示第三内容编码为“1”且第三地址编码为“0”的组合,用分子模块A25来表示第三内容编码为“1”且第三地址编码为“1”的组合。结合表示第二内容编码和第二地址编码的不同取值的组合的分子模块A10、分子模块A11、分子模块A12和分子模块A13,也可以完整地表示表14中的初始信息。这样,共需要7种不同的分子模块来表示8位2进制的初始信息。
在本公开的示例性实施例中,分子模块可以包括脱氧核糖核酸(DNA)、核糖核酸(RNA)、肽、有机聚合物、有机小分子、碳纳米材料、无机物、非天然核苷酸、经修饰的核苷酸或人工合成核苷酸等。在存储信息时,涉及表示内容编码和地址编码的不同分子模块的组装,这些分子模块之间可以以共价键、离子键、氢键、分子间作用力、疏水作用力、碱基互补配对等作用方式被组装在一起。
其中,表示同一种内容编码或地址编码的不同取值的不同分子模块可以是同种类型的分子模块,例如都为DNA。或者,表示同一种内容编码或地址编码的不同取值的不同分子模块可以是不同类型的分子模块,例如分别用一种DNA和一种RNA来表示一种内容编码的两种不同取值。此外,表示不同种类的内容编码或地址编码的分子模块可以是同种类型的分子模块,例如用不同的RNA来表示所有的内容编码和地址编码。或者,可以用不同类型的分子模块来分别表示不同种类的内容编码和地址编码,例如用RNA表示内容编码、用DNA表示地址编码等。
在按顺序来组装表示各种编码的分子模块时,表示地址编码的分子模块可以被组装在表示相应的内容编码的分子模块的前面、后面或插入在表示相应的内容编码的分子模块中间,这里不作限制。此外,表示某一地址编码或内容编码的分子模块也可以包括多个分子片段,这些分子片段也可以是间隔设置的。例如,表示第二地址编码的分子模块可以被组装在表示相应的第二内容编码的分子模块的前面、后面或插入在表示相应的第二内容编码的分子模块中间。
在本公开的一些实施例中,按照内容-地址对来存储信息,并且通过对信息的地址和/或内容进行重编码,反复利用预制的分子模块库中的分子模块进行大规模平行组装来实现信息存储,相比采用逐个生长核苷酸来合成DNA的方式存储信息,所需的分子模块的种类数目大幅减少,且平行组装大幅提高了组合的效率,从而降低了存储难度,改善了存储效率。然而可以理解的是,在其它一些实施例中,也可以采用其它方式来根据待存储的信息 确定相应的分子模块和组装顺序,在此不作限制。
返回图1,分子模块组装方法还可以包括:
步骤S200,根据所确定的分子模块和组装顺序生成组装信号;以及
步骤S300,基于组装信号,利用分子模块组装设备来讲分子模块组装为用于存储信息的分子。
其中,组装信号的具体形式可以根据分子模块组装设备来确定,且组装信号可以包括一个或多个信号,分别用于分子模块组装设备中的相应部件的控制,从而驱动分子模块的组装至少部分自动地运行。
在本公开的示例性实施例中,分子模块组装设备可以基于介电润湿效应来驱动包含分子模块的液滴的移动,从而将多种分子模块组装为用于存储信息的分子。如图8所示,该分子模块组装设备可以包括多个微流控器件100,多个微流控器件100可以呈阵列状排布。在图8所示的具体示例中,分子模块组装设备包括共7x12个微流控器件100,且这84个微流控器件100呈矩形阵列状排布。然而可以理解的是,在其它一些实施例中,可以根据需要来改变微流控器件100阵列的行数和列数,此外,多个微流控器件100也可以被排布为其它非矩形的阵列,以满足相应的需求,在此不作限制。
此外,在一些实施例中,如图8所示,分子模块组装设备还可以包括多个液滴源200,多个液滴源200中的每个液滴源200可以分别被配置为提供包含相应的分子模块的液滴。其中,液滴源200所提供的液滴的大小可以在皮升至微升的量级上,例如从10皮升至100微升的体积。在一具体示例中,不同的液滴源200所提供的液滴中所包含的分子模块可以是不同的。这样的液滴源200的数量可以等于用于存储信息的分子中所包含的分子模块的种类数量。在另一具体示例中,为了提高分子模块的组装效率,一些液滴源200所提供的液滴中包含的分子模块可以是相同的,以更高效地提供例如使用频率更高的分子模块。另外,在组装分子模块的过程中,可能还需要在某些分子模块之间添加用于连接的其它分子模块(例如,连接酶)等,相应地,一些液滴源200也可以提供包含这样的分子模块的液滴。通常情况下,液滴源200可以靠近多个微流控器件100中的部分微流控器件100设置,以将液滴提供给相应的微流控器件100。在图8所示的具体示例中,为了给分子模块的组装预留出足够的空间,液滴源200可以集中设置在分子模块组装设备的一侧上。然而可以理解的是,在其它一些实施例中,根据期望的液滴移动路径,也可以相应地改变液滴源200在分子模块组装设备中的位置,在此不作限制。另外,还需要理解的是,在一些实施例中,也可以直接在部分微流控器件100上提供包含各种分子模块的大液滴,在后续的组装步骤中,可以从这些大 液滴中分离出实际参与组装的小液滴,那么在这种情况下,也可以不在分子模块组装设备中设置专门的液滴源。
如图9至图11所示,每个微流控器件100可以包括第一电极111和第二电极121,且每个微流控器件100可以被配置为通过施加在第一电极111与第二电极121之间的电压来控制处于该微流控器件100中的包含分子模块的液滴900的移动,使得分子模块组装设备中的至少两个液滴被混合以组装至少两种分子模块。
具体而言,图9和图10示出了在一种微流控器件100中液滴900的不同状态。其中,图9和图10各自描绘了分子模块组装设备中的两个微流控器件100(在图中用虚线间隔开这两个微流控器件以便识别)。在图9和图10所示的微流控器件100中,同一个微流控器件100中的第一电极111和第二电极121设于不同的平面上,且第一电极111和第二电极121彼此相对设置。
在图9中,两个微流控器件100的第一电极111和第二电极121之间都没有施加电压,这样,液滴900的接触角可以被表示为θ1。
在图10中,左侧的微流控器件100的第一电极111和第二电极121之间没有施加电压,而右侧的微流控器件100的第一电极111和第二电极121之间施加了电压U,这样,由于介电润湿效应的作用,液滴900右侧的接触角从θ1减小为θ2,换句话说,右侧的微流控器件100对液滴900的浸润性变得更加亲水。当液滴900与右侧的微流控器件100的第一电极111之间的接触角减小到一定程度时,液滴900将向施加有电压的微流控器件100的方向移动。具体而言,液滴的接触角和施加在第一电极上的电压U(这里,第二电极接地)之间的关系满足其中,εr表示第一介电层(后文中将详细描述)的相对介电常数,ε0表示真空介电常数,d表示第一介电层的厚度,以及γlg表示气-液表面张力。这样,基于介电润湿效应,通过按照预设时序向相应的微流控器件100施加电压,可以驱动分子模块组装设备中的液滴900按照期望的路径移动,进而实现分子模块的组装。
此外,虽然在最简单的微流控器件100中,液滴900可以与第一电极111和/或第二电极121直接接触,但这通常会导致液滴900与电极之间发生电解反应,进而导致液滴900中所包含的分子模块发生变化。为了解决这一问题,在一些实施例中,如图9和图10所示,微流控器件100还可以包括第一介电层112和第二介电层122中的至少一者。其中,第一介电层112可以设于第一电极111的更靠近液滴900的一侧上。类似地,第二介电层122可以设于第二导电电极121的更靠近液滴900的一侧上。介电层可以由一种或多种介电材料形成。在一具体示例中,如果电压被施加在第一电极111上,而第二电极121接地,那么可以省去第二 介电层122。介电层可以有效地避免液滴直接接触电极所引起的电解反应等,还可以充当相邻电极之间的电介质以使得各个电极能够被单独地控制,从而保证分子模块的组装能够按照期望的方式进行。
在一些实施例中,第一介电层112和第二介电层122中的至少一者可以由疏水性材料形成,例如,由包括有机介电材料等的介电材料形成。在这种情况下,介电层可以与液滴直接接触,且由于介电层的表面是疏水性的,可以避免液滴铺展在介电层上,使得相应的分子模块可以被很好地限制在液滴中,而不会发生不期望的流动或混合。
在一些实施例中,尤其是在第一介电层112和/或第二介电层122本身的浸润性较好的情况下,如图9和图10所示,微流控器件100还可以包括第一疏水层113和第二疏水层123中的至少一者。其中,第一疏水层113可以设于第一介电层112的更靠近液滴900的一侧上,与液滴900直接接触。类似地,第二疏水层123可以设于第二介电层122的更靠近液滴900的一侧上,与液滴900直接接触。通过设置第一疏水层113和/或第二疏水层123,可以使得分子模块组装设备中的液滴900保持为球形或基本球形的形状,以避免液滴铺展在介电层上,使得相应的分子模块可以被很好地限制在液滴中,而不会发生不期望的流动或混合。
进一步地,在一些实施例中,分子模块组装设备还可以包括彼此相对设置的第一基板和第二基板,多个微流控器件中的第一电极111、可能存在的第一介电层112和第一疏水层113可以设置在第一基板上。类似地,多个微流控器件中的第二电极121、可能存在的第二介电层122和第二疏水层123可以设置在第二基板上。基板可以起到对微流控器件的支撑作用。当然,可以理解的是,如果第一电极和/或第二电极等部件本身具有足够的机械强度,也可以不设置相应的基板。
在一些实施例中,相对设置的第一基板和第二基板可以由若干个间隔件分隔开,且第一基板和第二基板之间可以由空气填充,即液滴在空气中移动。
在一些实施例中,微流控器件还可以包括流体填充层,该流体填充层可以设于第一基板与第二基板之间,流体填充层与液滴不相容,且液滴可以被配置为在流体填充层内移动。例如,可以在第一基板和第二基板之间填充硅油,以使得液滴更顺畅地移动,降低驱动液滴移动所需的电压,提高组装效率。或者,在一些实施例中,也可以在液滴中添加合适的表面活性剂,以降低驱动液滴移动所需的电压。
如图11所示,在另一具体实施例中,同一个微流控器件100中的第一电极111和第二电极121可以设于同一平面上。通过将第一电极111和第二电极121设置在同一平面上,可以简化微流控器件100的立体结构,且在分子模块组装设备的运行过程中,可以更方便地观察 和监测液滴的移动。
如图11所示,在一些实施例中,微流控器件100还可以包括介电层102,该介电层102可以设于第一电极111和第二电极121的更靠近液滴的一侧上。介电层102可以由一种或多种介电材料形成,以有效地避免液滴直接接触电极所引起的电解反应等,还可以充当相邻电极之间的电介质以使得各个电极能够被单独地控制,从而保证分子模块的组装能够按照期望的方式进行。
在一些实施例中,介电层102可以由疏水性材料形成,例如,由包括有机介电材料等的介电材料形成。在这种情况下,介电层102可以与液滴直接接触,且由于介电层102的表面是疏水性的,可以避免液滴铺展在介电层102上,使得相应的分子模块可以被很好地限制在液滴中,而不会发生不期望的流动或混合。
在一些实施例中,尤其是在介电层102本身的浸润性较好的情况下,如图11所示,微流控器件100还可以包括疏水层103。其中,疏水层103可以设于介电层102的更靠近液滴的一侧上,与液滴直接接触。通过设置疏水层103,可以使得分子模块组装设备中的液滴保持为球形或基本球形的形状,以避免液滴铺展在介电层上,使得相应的分子模块可以被很好地限制在液滴中,而不会发生不期望的流动或混合。
进一步地,在一些实施例中,分子模块组装设备还可以包括基板,第一电极111、第二电极121以及可能存在的介电层102和疏水层103可以被设置在基板上。基板可以起到对微流控器件的支撑作用。当然,可以理解的是,如果第一电极和/或第二电极等部件本身具有足够的机械强度,也可以不设置相应的基板。
在另一些实施例中,分子模块组装设备可以包括彼此相对设置的第一基板和第二基板,其中,多个微流控器件中的一部分微流控器件可以设置在第一基板上,而另一部分微流控器件可以设置在第二基板上。
如上文所述的,相对设置的第一基板和第二基板可以由若干个间隔件分隔开,且第一基板和第二基板之间可以由空气填充,即液滴在空气中移动。
类似地,微流控器件也可以包括流体填充层,该流体填充层可以设于第一基板与第二基板之间,流体填充层与液滴不相容,且液滴可以被配置为在流体填充层内移动。
在上文所述的第一电极与第二电极彼此相对设置的分子模块组装设备中,或者包含彼此相对设置的微流控器件的分子模块组装设备中,如图12所示,液滴900可以被配置为沿第一基板110和第二基板120中的至少一者移动,以充分利用分子模块组装设备中的竖直空间,尤其是在多个液滴900同时在第一基板110和第二基板120上移动的情况下,可以有效地 提高分子模块的组装效率。例如,考虑到需要一定的反应时间使得来自不同的液滴源的液滴中的分子模块充分反应,因此可以使反应中的液滴处于第二基板120上以进行反应,同时使未混合的液滴或混合完成的液滴沿第一基板110移动到期望的位置,即利用第一基板110进行液滴的转移,而利用第二基板120进行分子模块的反应。
在一些实施例中,液滴900可以被配置为在静电力的作用下在第一基板110与第二基板120之间移动。例如,通过在位于上方的第二基板120的相应区域中施加一电压,可以使得该区域下的液滴900被吸引到第二基板120上。在液滴900本身足够小的情况下,当液滴900在静电力作用下被吸引到第二基板120上后,可以去除产生静电力的电压,液滴900仍然可以保持在第二基板120上移动,而不会在重力作用下落回到第一基板110上。
在本公开的示例性实施例中,为了实现对各个微流控器件100的高效控制,如图13所示,每个微流控器件100还可以包括开关器件130。其中,开关器件130的源极(S)和漏极(D)中的一者可以连接到该微流控器件100的第一电极111,开关器件100的源极(S)和漏极(D)中的另一者可以被配置为接收相应的数据信号(图13中所示为开关器件的漏极(D)连接到第一电极111,而源极(S)用于接收数据信号),且开关器件的栅极(G)可以被配置为接收相应的扫描信号。扫描信号可以由分子模块组装设备中的扫描线200进行传输,而数据信号可以由分子模块组装设备中的数据线300进行传输。
进一步地,在图13的具体示例中,处于同一行的微流控器件100中的开关器件130可以连接到同一条用于传输扫描信号的扫描线200,且处于不同行的微流控器件100中的开关器件130可以分别连接到不同的扫描线200。更具体地说,处于同一行的开关器件130的栅极连接到同一条扫描线200,而处于不同行的开关器件130的栅极连接到不同的扫描线200。另外处于同一列的微流控器件100中的开关器件130可以连接到同一条用于传输数据信号的数据线300,且处于不同列的微流控器件100中的开关器件130可以分别连接到不同的数据线300。更具体地说,处于同一列的开关器件130的源极(或漏极)连接到同一条数据线300,而处于不同列的开关器件130的源极(或漏极)连接到不同的数据线300。这样,可以高效且独立地控制分子模块组装设备中的各个微流控器件100,使得液滴可以沿着期望的路径移动。
在一具体示例中,假设当开关器件130的栅极接收到高电平电压时,其源极和漏极之间导通,且当第一电极111接收到高电平电压时,处于该微流控器件中的液滴的接触角将变小而移动,那么,当与微流控器件100相连的扫描线200和数据线300均输出高电平电压时,该微流控器件100对应的液滴将移动。反之,只要与微流控器件100相连的扫描线200和数据 线300中的一者输出低电平电压,该微流控器件100对应的液滴将保持静止。在后文中,将以上述假设为前提进行具体的阐述。然而可以理解的是,在一些实施例中,开关器件130也可以在其栅极接收到低电平电压的情况下,源极和漏极之间导通;或者,当第一电极111接收到低电平电压时,处于该微流控器件中的液滴的接触角将变小而移动,在这些情况下,只要相应地调整数据信号和扫描信号来使得液滴沿期望的路径移动即可,在此不再赘述。
在一些实施例中,开关器件130可以包括薄膜晶体管。在这种情况下,可以基于制备薄膜晶体管阵列的方式来制备分子模块组装设备中的多个微流控器件。由于薄膜晶体管阵列中每个单元的尺寸可以在毫米或微米量级,因此每个微流控器件的尺度可以从厘米量级减小到毫米或微米量级,这样的微流控器件的尺寸可以大幅减小,同时可以实现对液滴移动的更精细的控制。
在另一些实施例中,开关器件130可以包括有机电化学晶体管。类似地,可以基于制备有机电化学晶体管阵列的方式来制备分子模块组装设备中的多个微流控器件,且每个微流控器件的尺寸可以足够小,同时实现对液滴移动的精细控制。此外,由于有机电化学晶体管本身的材料通常是疏水性的,在这种情况下,还可以省略有机电化学晶体管阵列层上的疏水层的设置,以进一步简化分子模块组装设备的结构。
图14至图19示出了一具体示例中分子模块的组装过程。在下文的描述中,将以(m,n)来表示位于从左到右数第m列、从上到下数第n行的微流控器件100的坐标。如图14所示,第一个液滴源200可以输出包含第一种分子模块的第一个液滴900,控制第一行扫描线上的扫描信号处于高电平电压,并控制第二、三、四列数据线上的数据信号依次处于高电平电压,可以使得第一个液滴沿坐标为(1,1),(2,1),(3,1)和(4,1)的微流控器件移动(如虚线箭头所指示的),并静止在坐标为(4,1)的微流控器件处。
如图15所示,第二个液滴源200可以输出包含第二种分子模块的第二个液滴900,通过控制第三行、第二行和第一行扫描线上的扫描信号依次处于高电平电压,并控制第一列数据线上的数据信号处于高电平电压,可以使得第二个液滴沿坐标为(1,3),(1,2)和(1,1)的微流控器件移动,然后控制第一行扫描线上的扫描信号处于高电平电压,并控制第二、三、四列数据线上的数据信号依次处于高电平电压,可以使得第二个液滴沿坐标为(1,1),(2,1),(3,1)和(4,1)的微流控器件移动(如虚线箭头所指示的),并静止在坐标为(4,1)的微流控器件处,与第一个液滴混合。在第一个液滴与第二个液滴混合后,其中的第一种分子模块和第二种分子模块将发生反应而组装。
类似地,如图16所示,第三个液滴源200可以输出包含第三种分子模块的第三个液滴 900,通过控制连接到相应的微流控器件的扫描线和数据线上的扫描信号和数据信号的电平,可以使得第三个液滴沿虚线箭头所指示的方向移动,并与之前的第一个液滴和第二个液滴混合,进而使得第三种分子模块也参与到组装过程中。
如图17所示,混合后的液滴可以沿虚线箭头所指示的方向移动,直至到达如图18所示的位置。在移动过程中,三种分子模块可以更好地混合以发生反应,从而产生与待存储的信息对应的分子。
在一些实施例中,多个微流控器件中的至少一个微流控器件还可以被配置为使得混合形成的液滴沿预设路径移动,该预设路径可以包括直线路径、折线路径和往复路径中的至少一者,也可以包括其它曲线路径。通过使混合后的液滴沿预设路径移动,一方面可以帮助液滴中各种分子模块更高效和更均匀地组装,另一方面可以将液滴移动到某些特定的位置(例如,移动到后文中所述的具有特定温度的位置),以更好地完成组装反应。
如图19所示,可以按照上文所述的方式混合液滴来产生其它的用于存储信息的分子,并将这些分子移动到分子模块组装设备中的相应位置上,以便进一步进行分离等处理。可以理解的是,为了给在后的液滴的混合或分子的组装预留足够的空间,以及尽可能并行地进行多种分子的组装过程,在先被混合或组装完成的液滴或分子可以被移动到距离液滴源较远的位置。
为了进一步提高分子模块的组装效率,在一些实施例中,多个微流控器件中的至少两个微流控器件可以被配置为使得其中的液滴同时地移动。如上文中所述的,由于同一行微流控器件共用一条扫描线,而同一列微流控器件共用一条数据线,因此在设计多个液滴的移动路径时,只要保证同一行或同一列中的液滴的移动不发生冲突即可。在一具体示例中,处于同一行中的液滴可以被同时地移动。在这种情况下,与这一行对应的扫描线上的扫描信号可以处于高电平电压状态,且多个列对应的多条数据线上的数据信号可以同时处于高电平电压状态,这样,处于多个列上的多个液滴将可以同时移动。
在一些实施例中,如图20至图22所示,多个微流控器件100中的至少两个微流控器件100可以被配置为使得液滴的两部分分别向不同的方向移动(如图20中的虚线箭头所指示的),以分裂液滴。
在一些实施例中,如图23所示,多个微流控器件100中的至少一个微流控器件100还可以包括温控器件140,该温控器件140可以被配置为控制处于该至少一个微流控器件100中的液滴的温度。在一具体示例中,该温控器件140可以包括例如微电阻器。
设置温控器件140是考虑到在一些分子模块的组装反应中,可能对反应温度存在特定 的要求,相应地,有必要对混合后的液滴的温度进行控制。假设在某一具体的组装反应中,需要混合后的液滴在第一温度T1下反应达第一时间t1,再在第二温度T2下反应达第二时间t2,最后在第三温度T3下反应达第三时间t3,那么可以通过两种方式来控制混合所得的液滴的温度。
在一种方式中,可以在分子模块组装设备中设置两个带有温控器件140的区域,通过施加相应的扫描信号和数据信号,使混合所得的液滴首先在具有第一温度T1的区域中停留第一时间t1;然后,使液滴移动到具有第二温度T2的区域中停留第二时间t2,与此同时,可以将之前液滴所处的区域的温度从第一温度T1调节到第三温度T3;最后,使液滴返回到目前具有第三温度T3的区域中停留第三时间t3,以完成反应。可以理解的是,在其它一些实施例中,也可以在分子模块组装设备中设置具有不同温度的三个或更多个区域,并通过施加相应的扫描信号和数据信号使液滴在期望的温度区域中停留达期望的时间。
在另一种方式中,可以保持混合所得的液滴的位置不变,而改变分子模块组装设备中包含温控器件140的区域的温度。具体而言,可以将相应的区域的温度调节到第一温度T1达第一时间t1,再迅速将温度调节到第二温度T2达第二时间t2,最后迅速将温度调节到第三温度T3达第三时间t3,以完成反应。
进一步地,为了监测温控器件的温度,多个微流控器件中的至少一个微流控器件还可以包括温度传感器,该温度传感器可以被配置为感测处于至少一个微流控器件中的液滴的温度。
在本公开的分子模块组装设备中,基于介电润湿效应来控制包含分子模块的液滴的移动,通过向微流控器件阵列中的各个微流控器件施加包含例如扫描信号和数据信号的相应的组装信号,可以实现包含分子模块的液滴的高通量定位定量分配,从而能够简洁、高效、精准地实现分子模块的组装,进而实现了在分子中存储信息。
该方法除应用于本文所描述的DNA数据存储方法外,还可以用于其它的高通量生化反应中,包括但不限于DNA组装、克隆、质粒构建、PCR扩增等。
