    • A device for controlling cell arrangement having a pattern composed of a cell adhesive surface and a cell non-adhesive surface, which has a good selectivity of cell adhesion and which can provide a fine pattern of cells in high resolution by culturing cells in a usual manner. The device is prepared by a process which comprises applying a photosensitive, cell adhesive or cell non-adhesive polymer to a surface having a reverse cell adhesivity property to that of the applied polymer, and patternwise irradiating a light to the photosensitive polymer layer followed by development; a process which comprises patternwise irradiating UV or radiation to a cell non-adhesive surface to produce a cell adhesive functional group such as carboxyl group or amino group in the irradiated portion; or a process which comprises patternwise irradiating UV or radiation to a cell adhesive or non-adhesive surface made of plastics to produce a polymerization initiation site in the irradiated portion, and graft-polymerizing at least one monomer having the reverse cell adhesivity property to the plastic surface to produce a polymer on the irradiated portion of plastic surface.

    • An anti-thrombogenic substance is immobilized on a base of a medical device to impart anti-thrombogenic properties to the medical device. The method comprises the steps of applying a photo-reactive azide derivative macromolecular material to a base to form a bonding layer, coating the bonding layer with a macromolecular layer composed of a water-soluble photo-crosslinking macromolecular material containing the anti-thrombogenic substance, and irradiating the base with ultraviolet light with the bonding layer and the macromolecular layer formed thereon to develop inter-molecular covalent bonding in the bonding layer. The macromolecular layer containing the anti-thrombogenic substance is thus fixed onto the base. Concurrently, the anti-thrombogenic substance is immobilized in the macromolecular layer which is crosslinked. The azide derivative can be poly-m-azidostyrene, copolymers, of poly-m-aziodstyrene with styrene and copolymers of poly-m-azidostyrene with methyl methacrylate. The water-soluble photo-crosslinking macromolecular material can be a copolymer of a photo-dimeric monomer with a water-soluble monomer or a copolymer of a photo-reactive azide with a water-soluble monomer.
    • 将抗血栓形成物质固定在医疗装置的基底上,以向医疗装置赋予抗血栓形成性质。 该方法包括以下步骤:将光反应性叠氮化物衍生物高分子材料施加到基底上以形成结合层,用包含抗血栓形成物质的水溶性光交联性高分子材料构成的高分子层涂覆粘合层, 并用形成在其上的接合层和高分子层的紫外线照射基底,以在接合层中形成分子间共价键。 因此将含有抗血栓形成物质的大分子层固定在基底上。 同时,抗血栓形成物质固定在交联的高分子层中。 叠氮衍生物可以是聚 - 间 - 叠氮基苯乙烯,聚 - 间 - 偶氮苯乙烯与苯乙烯的共聚物和聚 - 叠氮基苯乙烯与甲基丙烯酸甲酯的共聚物。 水溶性光交联高分子材料可以是光二聚单体与水溶性单体或光反应性叠氮化物与水溶性单体的共聚物的共聚物。
