    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.

The dispersant includes a polymer of vinyl monomer having a binding acidic group. When ? is a dimensionless number defined by an average particle size (nm) of the fine nano-oxide particles divided by nm, the polymer has a degree of polymerization of an integer of 3 or more and 8 ×? or less with the proviso that the integer is a numerical value obtained by dropping a decimal fraction. The composite material is produced through a step of obtaining a dispersant comprising a polymer by polymerizing a vinyl monomer having a binding acidic group in the presence of polyamine or in an aqueous dilute dispersion, and a step of mixing the dispersant, fine nano-oxide particles, and a transparent resin material.

  • Patent number: 8399584
    Abstract: Copolymers are manufactured to include a zwitterionic monomer (e.g., methacryloyloxyethyl phosphorylcholine monomer), a dihydroxyphenyl derivatized monomer, and optionally one or more additional monomers. The dihydroxyphenyl derivatized monomer gives the copolymers excellent adhesion properties. Optional monomers include a cationic amino monomer, a hydrocarbon monomer, and/or a hydrophilic monomer. The copolymers are biocompatible and can be used with medical devices.

  • Publication number: 20130059926
    Abstract: A method for producing polymerisable solution which comprises dissolving an ethylenically unsaturated zwitterionic monomer in a co-monomer system comprising a functionalised ethylenically unsaturated monomer in which the zwitterionic monomer is soluble, a siloxane group-containing monomer or macromer, and a crosslinking agent is disclosed. The polymerisable solution is biocompatible and can be used to produce polymers and articles such as contact lenses.
