초록

Polymer hydrogels are adapted for surgical implants by chemical modification of the surface to stimulate the attachment and growth of cells thereto. The modification may be by oxidative acid etching or by copolymerization with methacrylic acid and diethylaminoethyl methacrylate.

대표
청구항

An implantable material comprising a substrate having a surface and a polyHEMA hydrogel applied to said surface which is chemically modified by means of hydrolytic etching by an acid in order to alter the condition of said surface form a non-adhesive state to an adhesive state and thereby promote the attachment and growth of cells to said surface.
