【Abstract】 An overview is given of the research on magnetic nano particle in the living body. Magnetic nano particles found in the body of magnetic bacteria in the 1970’s provide definite proof of the relationship between magnetite and biology. We briefly describe the configuration and arrangement of magnetic nano particles in magnetic bacteria, and the mineralization process of magnetic nano particles in the radula teeth of chiton, as well as the relationship between supermagnetic particles and the neural system in the abdomen of honeybees, on which the concept and model of “magnetic acceptors”has been built. Finally, magnetic nano particles in the human cerebrum and their possible functions are discussed.更多还原
