ABSTRACT:
Support matrices for immobilized enzymes comprise a combined organic-inorganic support consisting of a porous inorganic support containing an organic polymeric material which possesses functionalized pendent groups, said polymeric material being entrapped and also adsorbed in part in the pores of the inorganic porous support. The organic polymeric component of the matrix constitutes a copolymer prepared in situ from a first polyfunctional monomer, a low molecular weight polymer, a low molecular weight polymer hydrolysate, or a preformed polymer of natural or synthetic origin which is reacted with an excess of a second bifunctional reactive monomer.
