The cantilever vibrates at its resonance frequency, lightly "tapping" the surface. This reduces friction and lateral forces, making it the gold standard for polymers and DNA .

It measures nanomechanical properties —how hard, elastic, or sticky a new composite material is at a specific point. Fundamentals and Application of Atomic Force Mi...

As the tip scanned across a surface, atomic forces (like Van der Waals, electrostatic, or capillary forces) cause the cantilever to deflect. The cantilever vibrates at its resonance frequency, lightly

AFM has moved far beyond simple "pictures." It is now a lab-on-a-tip: As the tip scanned across a surface, atomic

The core of an AFM is a with a sharp probe (tip) at its end. This tip typically has a radius of curvature on the scale of a few nanometers.

Researchers use AFM to visualize the double helix of DNA or the movement of protein channels in living cell membranes under physiological conditions (liquid environments).

The tip hovers just above the surface, sensing long-range forces. This is used for extremely hydrophobic surfaces or when the sample must remain completely untouched. 3. Key Applications
