To explore the preparation and characterization of a novel nanosized magnetic liposome containing the PEI-As(2)O(3)/Mn(0.5)Zn(0.5)Fe(2)O(4) complex. Mn(0.5)Zn(0.5)Fe(2)O(4) and As(2)O(3)/Mn(0.5)Zn(0.5)Fe(2)O(4) nanoparticles were prepared by chemical coprecipitation and loaded with PEI. The PEI- As(2)O(3)/Mn(0.5)Zn(0.5)Fe(2)O(4) complex was characterized using transmission electron and scanning
