Scanning Probe Microscopes (SPMs) are advanced tools used to visualize surfaces at the atomic level. They work by scanning a sharp probe over a sample's surface, measuring interactions between the probe and the atoms. This allows scientists to create detailed images and gather information about the sample's properties. There are various types of SPMs, including Atomic Force Microscopes (AFM) and Scanning Tunneling Microscopes (STM). Each type uses different techniques to achieve high-resolution imaging. SPMs are widely used in fields like materials science, nanotechnology, and biotechnology for research and development purposes.
