Atomic Force Microscope: Unlocking the Nanoscale World
In the realm of nanotechnology and material science, the Atomic Force Microscope (AFM) stands as one of the most powerful and versatile tools. Unlike traditional optical microscopes, which are limited by the wavelength of light, AFMs allow scientists to visualize, measure, and manipulate surfaces at the atomic and molecular level. This capability has made AFMs invaluable in research fields ranging from physics and chemistry to biology and engineering.
What is an Atomic Force Microscope?
An atomic force microscope is a type of scanning probe microscope that maps the surface of a material by “feeling” it with a mechanical probe rather than using light or electrons. It consists of a sharp tip mounted on a flexible cantilever. As the tip scans the surface of a sample, interactions between the tip and atoms of the sample cause the cantilever to deflect. A laser beam directed…
