Publication number: 20140011960Abstract: In analyzing, fractionating, and culturing cells alive, operations can be more simply made in real time and culture can be performed while removing unnecessary cells from cultured cells for purification. Desired cells are also analyzed and fractionated from the cultured cells to increase the purity, recovery rate, and viability of the cells. A cell-adhesive photocontrollable base material is used in which light irradiation causes the bond dissociation of a photolabile group comprising an O-nitrobenzyl skeleton to irreversibly change the surface of the irradiated portion thereof from that of the cell-adhesive material to that of a non-cell-adhesive material. Cell images are detected and analyzed to obtain the positional information of desired cells. Based on this information, areas among cells and a cell-adhesive photocontrollable material are cut by second light irradiation.Type: ApplicationFiled: February 6, 2012Publication date: January 9, 2014Inventors: Tomohiro Konno, Kazuhiko Ishihara, Batzaya Byambaa, Hisashi Sugiyama, Satoshi Ozawa
