Abstract
A process for providing enzyme activity to the surface of an article is described, comprising forming a film on the surface of the article, said film comprising an acid anhydride group-containing polymer and a polyol, wherein the acid anhydride groups are partially reacted with the polyol, and thereafter reacting the unreacted acid anhydride groups with an enzyme. Such an article provided with enzyme activity on the surface can be used for the production of food, medicines, etc., and as a medical material.
