Imaging and manipulating chromosomes by the atomic force microscope (CAT#: STEM-SMMT-0016-LJX)

Atomic force microscope (AFM) is a new type of surface analysis instrument based on the principles of physics and imaging through the interaction of scanning probe and sample surface atoms. It belongs to the third generation of microscopes after optical microscopes and electron microscopes.
AFM usually uses a sharp probe to scan the sample, which is fixed on a microcantilever that is extremely sensitive to the surface force between the probe and the sample. The deflection of the cantilever under force can cause the laser beam emitted by the laser source to shift after being reflected by the cantilever. The detector receives reflected light, and finally receives signals that are collected, processed, and formed into surface morphology images of the sample through a computer system.
