| Research Abstract |
I succeeded to synthesize iron oxide nano-particles (NPs) in a bio-template,apoferritin by some detail investigation of reaction conditions. A diameter of the synthesized NP in the apoferritin is about 5-6 nm and it can bind to Neodymium magnets. It is clear that the synthesized NP consist of Fe3O4 by the XRD, EDX analysis and HR-TEM observation. This NP is expected to generate heat for a hyperthermia effect. In addition, I also succeeded to synthesized CuS, FeS, and Ta NPs in the apoferritin cavity. The diameter of CuS NPs in the apoferritin cavity is 5 nm and it consists of Cu2S by the XRD, EDX analysis. I perform an elemental analysis of the other cores and magnetic observation. Recently, I constructed a plasmid of another apoferritin protein from human heart and I synthesized iron oxide NPs in this apoferritin. Since this apoferritin included NP and is suitable for our DDS and various nanotechnology applications, I continue to elucidate the magnetic character and some improvement of these NPs in the apoferritin.
