英文摘要：

Atomic force microscopy （AFM） with good signal-to-noiseratio, high spatial and time resolution, and flexible detection environments is one of the most excellent equipment in the research on biological sample in physiological condition. In this review, we introduce the applications of AFM to the surface structure of molecular motor, photo-system complex Ⅰ and Ⅱ, membrane channels and the chaperon and so forth, and following with the application in the details of various proteins molecules; stress on the studies in physical properties of single protein molecular such as surface viscidity and flexibility, surface charge and intermolecular interaction.
