The tip is dragged directly across the surface. While it provides high-resolution data for hard materials, the frictional forces can damage soft biological samples.

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.

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. The tip is dragged directly across the surface

Atomic force microscope (AFM), the key tool for surface analysis is the most versatile
