SUBSTRATE WITH PHOTO-CONTROLLABLE CELL ADHESION PROPERTY, METHOD FOR ANALYZING AND FRACTIONATING CELLS, AND DEVICE FOR ANALYSIS AND FRACTIONATION OF CELLS

摘要

When cells are analyzed, fractionated, and incubated while keeping the cells alive, real-time operations can be performed more easily and the cells can be incubated while removing unnecessary cells from the incubated cells to purify the cells being incubated. Furthermore, desired cells are separated through analysis from the incubated cells, and the purity, recovery, and viability of the cells are heightened. Use is made of a substrate having photo-controllable cell adhesion properties, the substrate comprising a transparent base and, formed thereon, a film of a material which has photo-controllable cell adhesion properties and has been obtained by bonding a cell-adhesive material to a cell-non-adhesive material through photo-dissociable groups. Cell images are detected and analyzed to obtain information about the location of desired cells. On the basis of the information, a space is formed between cells and the material having photo-controllable cell adhesion properties is cut, by means of second light irradiation. Meanwhile, by means of first light irradiation, the surface of the substrate is changed from a cell-adhesive surface to a cell-non-adhesive surface, thereby separating the cell(s) from the substrate. Thus, cells can be analyzed and fractionated while keeping the cells alive.
