Description

本発明は、試料基板ホルダに関し、特に試料を付与する試料基板の表面近傍を観察に適した試料基板ホルダ及びその利用方法に関する。   The present invention relates to a sample substrate holder, and more particularly to a sample substrate holder suitable for observing the vicinity of the surface of a sample substrate to which a sample is applied and a method of using the sample substrate holder.

従来、固−液界面近傍の観察は、液量が少ない場合には、試料基板材料の表面に液滴を落とし、それを背面から観察することで行われている。また、細胞と基板材料との接着状態を観察するような場合は、十分な液量を長期にわたって保持する必要があり、底面に表面処理を施した培養ディッシュなどが用いられている(特許文献1、2、3参照)。   Conventionally, the observation of the vicinity of the solid-liquid interface is performed by dropping a droplet on the surface of the sample substrate material and observing it from the back when the amount of liquid is small. Moreover, when observing the adhesion state between the cells and the substrate material, it is necessary to maintain a sufficient amount of liquid over a long period of time, and a culture dish or the like having a surface treated on the bottom surface is used (Patent Document 1). 2, 3).

従来、次のような構成のものが利用されている。
1)細胞と基板材料との相互作用を制御する場合、底面に表面処理を施した培養ディッシュなどが用いられている。例えば、温度応答性高分子で全面被覆した基材表面で細胞を培養し、温度変化によって培養細胞を剥離回収する構成は知られている(特許文献1参照)。又、温度応答性分子でパターン状に被覆した基材表面で細胞を培養し、温度制御によって複数種の細胞パターンに沿って共培養する構成が知られている(特許文献2参照)。
Conventionally, the following configuration is used.
1) When controlling the interaction between a cell and a substrate material, a culture dish or the like having a surface treated on the bottom surface is used. For example, a configuration is known in which cells are cultured on the surface of a substrate that is entirely covered with a temperature-responsive polymer, and the cultured cells are peeled and recovered by temperature change (see Patent Document 1). In addition, a configuration is known in which cells are cultured on a substrate surface coated with a temperature-responsive molecule in a pattern, and co-cultured along a plurality of cell patterns by temperature control (see Patent Document 2).

2)平板状の基板にスピンコートや均一なプラズマ照射を含む様々な表面処理を施した構成が用いられている。例えば、温度応答性ポリマーの支持体への被覆方法として、電子線照射、γ線照射、紫外線照射、プラズマ処理、コロナ処理、有機重合反応、混練する構成が知られている(特許文献3参照)。 2) A structure in which a flat substrate is subjected to various surface treatments including spin coating and uniform plasma irradiation is used. For example, as a method of coating a support with a temperature-responsive polymer, electron beam irradiation, γ-ray irradiation, ultraviolet irradiation, plasma treatment, corona treatment, organic polymerization reaction, and kneading are known (see Patent Document 3). .

3)スライドガラスなどの表面に接着あるいは粘着によって仕切りを張り合わせ、平板状の基板表面を容器部(容器)の底壁(底面)とするキュベットが利用化されている(特許文献4、5参照)。

3) A cuvette having a flat substrate surface as a bottom wall (bottom surface) of a container part (container) is used by adhering partitions to the surface of a slide glass or the like by adhesion or adhesion (see Patent Documents 4 and 5). .
Japanese Patent Publication No. 06-104061 Japanese Patent Laid-Open No. 4-94679 JP 2003-38170 A JP-A-6-113815 JP 2002-125656 A

細胞と基板材料との相互作用などを観察する場合、底面に表面処理を施した培養ディッシュなどが用いられているが、底面はディッシュと一体になっており、表面処理の手法は限られてしまう。   When observing the interaction between cells and substrate materials, etc., a culture dish with surface treatment on the bottom surface is used, but the bottom surface is integrated with the dish, and surface treatment techniques are limited. .

一方、平板状の基板は、スピンコートや均一なプラズマ照射を含む様々な表面処理法に適応可能であるが、そのままの状態で固−液界面を観察するには、必要量の試料液体をその上に安定に保持することは困難である。   On the other hand, a flat substrate can be applied to various surface treatment methods including spin coating and uniform plasma irradiation. However, in order to observe the solid-liquid interface as it is, a necessary amount of sample liquid is added. It is difficult to keep it stable on top.

スライドガラスなどの表面に接着あるいは粘着によって仕切りを張り合わせ、平板状の基板表面を容器底面とするキュベットが既に実用化されているが、あくまでアッセイを簡便に行うことを目的としたもので、材料表面に対する接着あるいは粘着による張り合わせでは、様々な表面処理に適用することは難しい。   Cuvettes with a flat plate surface on the bottom of the container have already been put into practical use by attaching partitions to the surface of glass slides, etc., but the purpose of this is simply to perform the assay. It is difficult to apply to various surface treatments by bonding or sticking to each other.
