Description

基于纳米粒子的身份识别
技术领域
此专利是应用纳米粒子点混合物对条形码信息的安全和保护。
背景技术
基于纳米粒子的身份识别专利是应用纳米粒子点混合物对条形码信息的安全和保护。身份编码及并发读出器是通过纳米粒子微粒混合物的特殊光谱特性而研制，该点混合物是微小不可见的点，由可吸收的和可发荧光的纳米粒子组成，其光谱属性将会应用于安全身份识别标志。
发明内容
身份编码及并发读出器是通过纳米粒子微粒混合物的特殊光谱特性而研制，该点混合物是微小不可见的点，由可吸收的和可发荧光的纳米粒子组成，其光谱属性将会应用于安全身份识别标志。这些纳米粒子的类型通常涉及到量子点；它们或者是半导体或者是稀土元素。同时，在光谱的可见和近红外线部分，它们有窄吸收和发射频带。峰值的窄小使使用个体的吸收/发射特征作为独特的荧光条形码识别标志成为可能。因此纳米粒子的多样组合允许多个读出峰值，其充分地增大了编码信息的数量(见图2)。此外，混合物中纳米粒子浓度的变化，可进一步增加编码信息数量。每一类型纳米粒子的吸收/发射强度可以区别开不同浓度的纳米点混合物。
编码信息的读出可通过带有激发源和探测器的特殊设备实现。这个设备可基于宽带或类似激光的，窄带激发方法。前者方法使用宽带激发源，可根据强度进行区分。在此方法下，读出器的高分辨率胜过运转的相对缓慢速度，我们计划储存大量的应用信息。另一方法是基于类似激光激发源的窄带提供快速途径给读出器。读出器设备可针对两种方法设计，都可便携。
附图说明
对于一个物体或有效的标识物体，在其点混合物内，基于纳米粒子的身份识别系统可通过纳米粒子的定义混合物的微缩沉淀液滴实现(见图1)。纳米粒子可预混合或不断沉淀。纳米粒子独有的荧光色组合给出每一个点混合物特有的指纹印(见图3)。峰值的窄小使使用个体的吸收/发射特征作为独特的荧光条形码识别标志成为可能。因此纳米粒子的多样组合允许多个读出峰值，其充分地增大了编码信息的数量(见图2)。编码“标志”的读出器意味着获得点的光谱参数。
具体实施方式
纳米粒子的点混合物的主应用区是同假冒伪劣产品斗争并为材料及产品选择提供安全保护。点混合物的微型尺寸使其不可见，从而产生商品选择的“隐型商标”。该技术可应用于药物产品，食品，饮料，酒，香烟，中药，化妆品，钻石，珠宝，工艺品，纸币，服装，身份证等其他需求独一无二鉴定的有形物体。
