Chitosan modified magnetic nanocomposites were synthesized by the chemical cross linking method. Physicochemical properties including the morphology
phase composition
particle size and magnetic properties were characterized by TEM
FTIR
particle size analyzer and VSM. It was proved that the modified magnetic nanocomposites had corn-shell structure. The magnetic nanocomposites with adriamycin were synthesized by the ultrasonic method. The encapsulation efficiency of magnetic nanocomposites was analyzed by UV-Vis spectrophotometry
and the average entrapment efficiency was up to 46.13%
then further determined by MTT colorimetric method proved that the inclusion compound had obvious biological inhibition of K150 cells. The results showed that the magnetic nanomaterials had good biocompatibility and drug loading activity.
