Preparation of magnetic poly(methylmethacrylate-divinylbenzene-glycidylmethacrylate) microspheres by spraying suspension polymerization and their use for protein adsorption

Moderately uniform magnetic poly(methylmethacrylate-divinylbenzene-glycidyimethacrylate) microspheres (poly(MMA-DVB-GMA) microspheres) were prepared by spraying suspension copolymerization of methyl methacrylate, divinylbenzene and glycidyl methacrylate in the presence of Fe3O4 magnetic fluid. A protein adsorption assay indicated that these magnetic microspheres could significantly improve the capacity of protein adsorption. (c) 2005 Published by Elsevier B.V.
