    Abstract: 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.

  • Publication number: 20100125123
    Abstract: Metallized polyhedral oligomeric silsesquioxanes and metallized polyhedral oligomeric silicates are used as cure promoters, catalysts, and alloying agents for the reinforcement of polymer microstructures, including polymer coils, domains, chains, and segments, at the molecular level. Because of their tailorable compatibility with polymers, polyhedral oligomeric metallosesquioxanes (POMS) can be readily and selectively incorporated into polymers by common mixing processes.

  • Publication number: 20090306304
    Abstract: It is an object of the present invention to provide a crosslinked (meth)acrylic acid-type copolymer excellent in stability to a solvent, which causes substantially no crack due to drying when applied onto the surface of a current collector, and a secondary-cell electrode using the copolymer. The present invention relates to a crosslinked (meth)acrylic acid-type copolymer obtained by the steps of: polymerization of a (meth)acrylic acid imino compound represented by the general formula (1): (in the formula (1), R represents a hydrogen atom or a methyl group) and a (meth)acrylic acid ester in the presence of a crosslinking agent, and nitroxidation.

  • Publication number: 20090206330
    Abstract: An organic insulator composition according to example embodiments may include an organic insulating polymer and an epoxy-based crosslinking agent. The epoxy-based crosslinking agent may have an alkyl group or a fluorine-based side chain. The organic insulator composition may be used to form an organic insulating layer having increased chemical resistance. The organic insulating layer may be used in an organic thin film transistor as a gate insulating layer. Consequently, the occurrence of hysteresis may be reduced or prevented during the operation of the organic thin film transistor, thus resulting in relatively homogeneous properties.
