Lysine chemically modified chitoan with good water solubility was synthesized in this paper
and the optimizing coordination condition was carried out. Its composition and structure was characterized by FT-IR and
1
HNMR
and it was used as matrix to prepare magnetic microspheres. The microspheres were analysised by XPS
TEM
XRD and VSM. The resultes showed that the particles were spherical and uniform in dimension with particle diametrers of100nm
and had good supermagnetic characterization
there were also many amidos on their surface. All the investigation indicated lysine modified chitosan magnetic microspheres would be used as a good gene delivery system in future.
