The main techniques for protein structure analysis include X-ray crystallography, nuclear magnetic resonance spectroscopy (NMR), cryo-electron microscopy (Cryo-EM), and atomic force microscopy (AFM). Here is a brief introduction in the following. X-Ray Crystallography 1. ...
A stylus profilometer provides roughness results by running a contact probe along a path on the sample. The stylus is relatively inexpensive; however, it only provides 2D results along a pathway or profile, and it may damage the very surface it measures. An atomic force microscope (AFM) uses a very small cantilever probe that is brought into ...
Scanning probe lithography and molecular self-assembly have been integrated for constructing surface nanostructures. In the first part of this paper, organosilane monolayers grown through molecular self-assembly, i.e., self-assembled monolayers (SAMs) are applied as patterning media in scanning probe lithography based on scanning tunnelling microscopy (STM) and ...
We review the application of atomic force microscopy (AFM) and magnetic tweezers for probing cell nanomechanics. AFM measures the mechanical properties of the cell by indenting its surface by means of a flexible cantilever with a sharp tip at its end. Magnetic tweezers probe cell mechanics by twisting or pulling a magnetic ...
The boundary support conditions of micromechanical structures such as AFM probes are non-classical in nature, and they influence the modal response and natural frequencies of the cantilever that cannot be modelled on purely classical boundary conditions. In this paper, an AFM cantilever end support is modelled with artificial translational and ...
