AFM’s ability to work in various environments—including air, vacuum, and liquids—has led to breakthroughs in several fields:

The tip hovers just above the surface, oscillating at its resonance frequency. It detects attractive forces without touching the sample, making it ideal for the most fragile specimens. Scanning Probe Microscopy: Atomic Force Microsc...

At its core, an AFM operates much like a record player. It uses a microscopic probe, usually made of silicon or silicon nitride, attached to a flexible cantilever. As the probe scans across a surface, atomic-scale forces (such as , electrostatic, or capillary forces) cause the cantilever to bend or vibrate.

Scanning Probe Microscopy (SPM) transformed our understanding of the nanoworld by allowing scientists to "feel" rather than just "see" atoms. Among the various SPM techniques, is the most versatile, capable of imaging nearly any surface—from hard semiconductors to soft living cells—at sub-nanometer resolution.
