Radiation synthesis and magnetic properties of novel Co0.7Fe0.3/Chitosan compound nanoparticles for targeted drug carrier

Chitosan coated Co0.7Fe0.3 compound nanoparticles were successfully synthesized through a γ-radiation route in inverse microemulsion system. An observation of transmission electron microscope (TEM) showed that the diameter of these nanoparticles was about 50 nm with narrow size-distribution. Investigations of properties of nanoparticles were also conducted with fourier transform infrared spectrometer (FT-IR), X-ray diffraction (XRD) and energy dispersion spectrum (EDS). Analysis of vibrating sample magnetometer (VSM) indicated that the nanoparticles were superparamagnetic with a saturation magnetization of 24 emu/g. These compound nanoparticles were undertaken to allow for the magnetically targeted cancer.
