Atomic Force Microscopy (AFM) plays important roles in nanobiology. We here review the recent development and application of AFM technology from the technical point of view. In the visualization mode, AFM produces not only static images at lower time-resolution in the seconds to minutes, but also motion images at higher time-resolution in the milliseconds. Furthermore, AFM combined with fluorescent techniques can now address varieties of biological questions from genes to proteins and from proteins to cells. In the force mode, the tip directly interacts with the molecules of interests to measure the inter- and/or intra-molecular physical properties.
