Abstract:
A preparation m ethod o f composite m icrospheres is repo rted. The magnetic nano-CFe2O3 /chitosan composite m icrospheres are prepared by the suspension cross-link ing technique in the presence of magnet ic nano-C-Fe2O3 in one step. The properties of size, morpho logy, and magnetization are studied by some test ing means. It is found tha t the prepared composite m icrospheres are of core-mu ltishe ll type. The spherica lmorpho logy is observed and the size distribution is abou t 300 nm. The compositem icrospheres possess exce llent slow-re lease effect as carriers of bov ine serum album in.
