Preparation and characterization of nanobiocomposites containing iron nanoparticles prepared from blood and coated with chitosan and gelatin

In this study, we report the preparation of magnetic iron nanoparticles (INPs) from goat blood using incineration method. FT-IR and XRD studies have confirmed that the prepared nanoparticles were INPs. These INPs were coated with a mixture of chitosan and gelatin to prepare INP–CG nanobiocomposite and the TEM picture of these composite particles has shown an average particle size of 80–300 nm. MRI scan exhibited magnetic property and VSM studies revealed a magnetic saturation of 18.97 emu/g. This may be used as a MRI contrast agent to enhance cellular imaging and as magnetic nanocarrier for targeted delivery of drugs in the diagnosis and treatment of cancer.
