Study on space morphology of micromolecule structure of some biologic samples by AFM

In this paper, the space morphologies of micromolecule structure of some biologic samples were studied by AFM.IPC-208B, which was successfully developed by Chongqing University. AFM.IPC-208B is a high-resolution AFM, and its lateral and vertical resolution can reach 0.1 nm and 0.01 nm, respectively. The space morphologies of molecular structure of glutathione adulterated with zinc ion, target gene and sheep anti human immunoglobulin-IgG were observed by AFM.IPC-208B, and their structural parameters were also measured. The space morphologies of molecular structure of the above materials have never been seen in home and abroad reports.
