摘要：

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. (C) 2011 Elsevier Ltd.
