To translate this physical bending into data, a laser beam is reflected off the back of the cantilever onto a . Even minute movements of the tip shift the laser’s path, which the detector records to generate a precise 3D topographic map of the surface. Primary Imaging Modes
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 Principles of Atomic Force Microscopy Scanning Probe Microscopy: Atomic Force Microsc...
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. To translate this physical bending into data, a
