How an atomic force microscope works
WebMost people know that you can't see atoms... or can you? In the late 1970s, two physicists in Switzerland set out to invent a new type of microscope using qu... WebInteracting forces. With AFM, one can measure the force between atoms at the tip and the sample which are located as close as 0.1–100 nm. The forces can be classified into attractive and repulsive forces. For attractive forces, van derWaals (vdW) interaction, electrostatic force and chemical force are included.
