Title:
ADHESION INHIBITOR FOR BIOMATERIAL AND CELLS
Document Type and Number:
WIPO Patent Application WO/2013/051479
Kind Code:
A1
Abstract:
[Problem] To provide a composition for forming a coating film that effectively inhibits the adhesion of cells such as platelets and a biomaterial such as a protein. [Solution] The invention provides an adhesion inhibitor, for cells and a biomaterial, comprising a polymer having a structural unit represented by formula (1), a crosslinking material, and an organic solvent. In formula (1), R1 represents a C4‑20 organic group containing one or two aromatic or alicyclic hydrocarbons, each n represents an integer from 5 to 600, and Q represents either formula (2), (3), (4), or (5) (in formula (2), Q1 represents a dihydric organic group, and each m independently represents either 0 or 1, and in formulas (3), (4), and (5), R2, R3, R4, and R5 each independently represents a hydrogen atom or an organic group).
