Abstract: Fe3O4 magnetic nanoparticles were as seeds and synthesized by the chemical co-precipitation and modified by bilayer surfactants. Styrene was as monomer in the emulsion polymerization ;And copolymerzation of both monomer with crylic acid and enfold Fe3O4.Use TEM observed: in the same experiment condition the magnetic microspheres of copolymerzation with crylic acid were enfolded better.And effects of adding methods of AA and its concentration on the content of magnetic microspheres surface carboxyl groups were studied.

Abstract: In the present work, technique of plasma polymerization was used to generate amido (- NH2) and carboxyl (-COOH) on titanium surface for immobilizing bovine serum albumin (BSA). After plasma polymerization of allylamine and crylic acid, the contact angle with respect to double distilled water significantly increased. Surface components were detected by X-ray photoelectron spectroscopy and Fourier transform infrared reflection-absorption spectroscopy. The results showed that BSA was successfully immobilized on the titanium surface and the amounts of BSA on specimens were relied on the properties of thin film deposited through plasma polymerization, which was corresponding to the ultraviolet spectrophotometer result.
