Abstract
A process for providing a surface of glass, silicon, aluminum or silicone rubber of an article useful within medicine with a bicompatible surface layer. Said surface is reacted (after oxidation when required) with a silane containing at least one epoxy group and the surface thus treated is then reacted with a polysaccharide containing at least one hydroxyl group. The invention also relates to an article exhibiting a biocompatible surface layer of a polysaccharide containing at least one hydroxyl group, which polysaccharide is covalently bound to a surface of glass, silicon, aluminum or silicone rubber of the article by means of a silane.
