Progress in the applications of high-speed atomic force microscopy in cell biology / 南方医科大学学报

ABSTRACT

Without losing its high resolution, high-speed atomic force microscope (HS-AFM) represents a perfect combinationof scanning speed and precision and allows real-time and observation of the dynamic processes in a biological system atboth the cellular and molecular levels. By combining the extremely high temporal resolution with the spatial resolution andcoupling with other advanced technologies, HS-AFM shows promising prospects for applications in life sciences such as cellbiology. In this review, we summarize the latest progress of HS-AFM in the field of cell biology, and discuss the impact ofenvironmental factors on conformation dynamics of DNA, the binding processes between DNA and protein, the domainchanges of membrane proteins, motility of myosin, and surface structure changes of living cells.
