Force Spectroscopy with the Atomic Force Microscope
Introduction and Review Atomic Force Microscope (AFM) Spectroscopy is an AFM based technique to measure, and sometimes control the polarity and strength of the interaction between the AFM tip and the sample. Although the tip-sample interaction may be studied in terms of the energy, the quantity that is measured first is always the tip-sample force, and thus the nomenclature: force spectroscopy....
متن کاملThe study of protein mechanics with the atomic force microscope.
The unfolding and folding of single protein molecules can be studied with an atomic force microscope (AFM). Many proteins with mechanical functions contain multiple, individually folded domains with similar structures. Protein engineering techniques have enabled the construction and expression of recombinant proteins that contain multiple copies of identical domains. Thus, the AFM in combinatio...
متن کاملPolymer Characterization with the Atomic Force Microscope
Atomic force microscopy is a powerful characterization tool for polymer science, capable of revealing surface structures with superior spatial resolution [1]. The universal character of repulsive forces between the tip and the sample, which are employed for surface analysis in AFM, enables examination of even single polymer molecules without disturbance of their integrity [2]. Being initially d...

as the molecules approach under the application of pressure. We expect that high-pressure Raman study will provide further insight into the vibrational and bonding properties in solid Cso The pressure behavior of a “squashing” mode, a radial distortion from the spherical shape into an ellipsoid, is particularly interesting in comparison with the softening observed for the IF,, radial mode. A hi...
