AFM has moved far beyond simple "pictures." It is now a lab-on-a-tip:

A laser beam reflects off the back of the cantilever onto a photodiode detector . Even a tiny movement of the tip translates into a measurable shift in the laser’s position. Fundamentals and Application of Atomic Force Mi...

AFM isn't "one size fits all." Depending on the sample's delicacy, researchers choose different modes: AFM has moved far beyond simple "pictures

To prevent the tip from crashing or losing contact, a piezoelectric scanner adjusts the height of the sample or the tip in real-time to maintain a constant force. This vertical movement is what creates the 3D topographic map. 2. Primary Imaging Modes This vertical movement is what creates the 3D

AFM is critical for quality control in microchip manufacturing, detecting defects that are far too small for optical tools.

The tip "drags" across the surface. It provides high resolution but can damage soft samples like biological tissues.

As the tip scanned across a surface, atomic forces (like Van der Waals, electrostatic, or capillary forces) cause the cantilever to deflect.
