Abstract:
Provided is a cell adhesion inhibitor which exhibits low cytotoxicity and an excellent cell adhesion prevention effect; a tool and an apparatus each having a surface modified through application of the cell adhesion inhibitor thereto; a method for producing each of the surface-modified tool and apparatus; a biomedical structure and a production method therefor; and a microchannel device and a production method therefor. The invention provides a cell adhesion inhibitor comprising, as an active ingredient, a polymer comprising a repeating unit having a sulfinyl group in a side chain thereof.

Claim (Index 18):
The method of  claim 17 , wherein the polymer comprising the repeating unit having a sulfinyl group in a side chain is represented by the following formula (2): wherein R 1  represents a hydrogen atom or a methyl group; R 2  represents *\u2014(C\u2550O)\u2014O\u2014 (* denotes a position of bonding to a carbon atom to which R 1  is bonded in formula (2)), or a phenylene group; R 3  represents a linkage group represented by the following formula (3) or a C1 to C24 alkanediyl group; and R 4  represents a monovalent group represented by the following formula (5) or a C1 to C10 alkyl group, wherein R 6  represents a single bond, \u2014R 8 \u2014O\u2014 (R 8  represents a C1 to C4 alkanediyl group), or a linkage group represented by the following formula (4); R 7  represents a C1 to C4 alkanediyl group; n is 1 or 2; and ** denotes the position of bonding to the sulfur atom in formula (2), wherein R 9  represents a C1 to C4 alkanediyl group; R 10  represents a C2 or C3 alkanediyl group; m 1  is 1 or 2; and m 2  is an integer of 1 to 3, wherein k 1  is an integer of 1 to 4; k 2  is an integer of 0 to 4; and *** denotes the position of bonding to the sulfur atom in formula (2).
