WebHow It Works. AFM operates in several modes. In contact mode, a tip that is attached to a cantilever is scanned over the sample surface, while the force between tip and sample is measured. While the tip is scanned laterally, the force is kept constant by moving the cantilever/tip assembly up and down, so that the deflection of the cantilever is ... 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. diagram of human chest

"WebHow AFM Works. An AFM cantilever with a protruding ultra-sharp tip is raster scanned over the sample, which makes either intermittent or constant contact with the surface. The tip interacts with the sample, experiencing repulsive or attractive inter-atomic forces. A laser beam is reflected off the back of the cantilever onto a detector.
