A novel magnetic polymer microsphere displaying photoconductivity was prepared by covalently bonding iron(III) phthalocyanine (FePc) onto a polystyrene microsphere with hydroxyl groups (PSA). PSA was synthesized by dispersion polymerization in the presence of Fe 3 O 4 magnetic fluid. The structure and properties of the magnetic polymer microsphere were identified by infrared spectoscopy. elemental analysis and scanning electron microscopy. The results showed that this kind of microsphere combines the merits of magnetic responsiveness and photoconductivity. The application of magnetic polymer microspheres for absorption of bovine serum albumin (BSA) was characterized at different temperatures, different incubation times, different pH values and different initial BSA concentrations. © 2002 Society of Chemical Industry
