発明の名称 (英語) POLYMER COMPOUND AND METHOD FOR MANIPULATING CELL USING SAME コモンズ
発明の概要(英語) Provided is a polymer compound which is changed from a water-insoluble state to a water-soluble state by irradiation with light. The polymer compound is represented by chemical formula (5), where: A and B each represent a single bond or a functional group; R3, R4, and R9 each represent hydrogen or an alkyl group; and R6 and R7 each represent hydrogen or an alkyl group, etc.
従来技術、競合技術の概要(英語) BACKGROUND ART
By an external stimulus to change the physical properties of the material is applied, in the field of bio-medical and the like have been studied actively. Such as proteins or cells handled as bio-devices, a large change in the properties of the material of the water is demanded. From human iPS cells have been considered for a full-scale utilization, the cells in culture is rapidly increasing in recent years the individual operating needs, the local action of the optical scale µm the properties of the utility of the material can be controlled to do.
To this, an increase in the wettability by light have been reported a polymer material. However, these polymer materials can be, not suitable for cell culture temperature and pH changes in physical properties, changes in physical properties is insufficient. In addition, have a photo-acid generator, a large change in optical properties of the polymeric material is reported. However, the polymeric material may, water soluble and insoluble to the control until the light has not reached. Further, the polymeric material may, by photo-cleavage reaction of the free or low-molecular weight component, such as with a strong acid, to limit the application of cell is also a problem. On the other hand, the material cross-linked by light is used for purposes such as photolithography. However, many of the material requires high temperature thermal treatment.
