Substrate for atomic force microscopy(原子力显微镜基片)

 

  Fluorphlogopite Mica (also called artificial mica, synthetic mica crystal) belongs to artificial mica crystal of silicate. It is the mica crystal which is smelted in a platinum crucible at the condition of high temperature of 1500, and the condition of process and the material ratio is controlled strictly. Because of its good flatness and no adsorption of impurities, Fluorphlogopite Mica has been used as the substrate for atomic force microscopy by Chinese Academy of Sciences Research Center of Environmental Biology, Peking University, Tsinghua University, Nanjing University, Shanghai Jiaotong University, Shanghai Fudan University and other national hundred scientific research units and colleges. Compared with traditional natural mica, Fluorphlogopite Mica has the better flatness and less adsorbed impurities. From the images observed at the analysis of structure of DNA, especially at the range of 1 nm -100 nm, we observed the surface interference fringes which can not be observed through natural mica, and the images are dozens of times clearer than the images observed through natural mica.

 

       This is the first time that the Fluorphlogopite Mica is applied to the biological field in China.
