While optical microscopes use light and electron microscopes use beams of electrons, Atomic Force Microscopy (AFM) works by "feeling" a surface—much like a record player needle or a person reading Braille. It is one of the most powerful tools in nanotechnology because it doesn't just see atoms; it interacts with them. 1. The Fundamentals: How It Works

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). Fundamentals and Application of Atomic Force Mi...

Works on samples without needing a gold coating. While optical microscopes use light and electron microscopes

As the tip scanned across a surface, atomic forces (like Van der Waals, electrostatic, or capillary forces) cause the cantilever to deflect. The Fundamentals: How It Works Researchers use AFM

The tip can be used as a "pen" to move individual molecules or etch patterns into a surface, enabling bottom-up nanofabrication . 4. Why Use AFM Over SEM? Unlike Scanning Electron Microscopy (SEM), AFM:
