| Abstract: | A novel route was presented for preparing nanoparticles by biosimulation chemical in-situ method.The monodisperse CoO nanoparticles were bio-mineralized by controlling the hydrolysis of metal Co ion and oxidation and reduction reaction with using horse spleen ferritin as controlled reactor.The magnetic CoO nanoparticles were obtained with apoferritin under the condition of alkalescence.The structure and compositions of the products were characterized by TEM and EDX,the particle size was 3~8 nm.In additional... |
