Atomic Force Microscopy Application in Biological Research: A Review Study
Atomic force microscopy (AFM) is a three-dimensional topographic technique with a high atomic resolution to measure surface roughness. AFM is a kind of scanning probe microscope, and its near-field technique is based on the interaction between a sharp tip and the atoms of the sample surface. There are several methods and many ways to modify the tip of the AFM to investigate surface properties, ...
متن کاملNoncontact atomic force microscopy
No other method has opened the door to progress in nanoscience and nanotechnology as much as the introduction of scanning probe methods did in the 1980s, since they offer a way to visualize the nanoworld. For maximum impact, however, the ability to image and manipulate individual atoms is the key. Initially, scanning tunneling microscopy was the only scanningprobe-based method that was able to ...
متن کاملIntermodulation atomic force microscopy
A mode of atomic force microscopy AFM is demonstrated where an oscillating AFM cantilever having linear response is driven with two frequencies in the vicinity of a resonance. New frequencies in the response, known as intermodulation products, are generated when the linearity of the cantilever response is perturbed by the nonlinear tip-surface interaction. A rich structure of the intermodulatio...
متن کاملAtomic Force Microscopy
Scanning probe microscopy (SPM) has revolutionised high resolution imaging of a wide range of samples. With the introduction of atomic force microscopy (AFM) high resolution images can be obtained without the need for the sample to be placed in a vacuum chamber. Furthermore, modern AFM systems are capable of producing high quality images of samples immersed in a wide range of liquids. Atomic Fo...
