Catch bonds were first proposed in 1988 in the Proceedings of the Royal Society by M. Dembo et al. while at Los Alamos National Laboratory.While developing molecular model to study the critical tension required to detach a membrane bound to a surface through adhesion molecules, it was found that it is theoretically possible for bond dissociation to be increased by force, decreased by force ...
Cross-sectional view of the structures that can be formed by phospholipids in an aqueous solution. A biological membrane, biomembrane or cell membrane is a selectively permeable membrane that separates the interior of a cell from the external environment or creates intracellular compartments by serving as a boundary between one part of the cell and another.
NanoWorld is the global market leader for tips for scanning probe microscopy (SPM) and atomic force microscopy (AFM). The atomic force microscope (AFM) is the defining instrument for the whole field of nanoscience and nanotechnology. It enables its users in research and high-tech industry to investigate materials at the atomic scale.
The common methods in nanobiomechanics include atomic force microscopy (AFM), nanoindentation, and application of nanoparticles. [6] [7] [8] These and other methods may be applied to relevant materials, for example: bone [6] and its hierarchical constituents such as single collagen fibrils, single living cells, actin filaments and microtubules.

Kelvin probe force microscopy (KPFM), also known as surface potential microscopy, is a noncontact variant of atomic force microscopy (AFM). [ 1 ] [ 2 ] [ 3 ] By raster scanning in the x,y plane the work function of the sample can be locally mapped for correlation with sample features.
Non-contact atomic force microscopy (nc-AFM), also known as dynamic force microscopy (DFM), is a mode of atomic force microscopy, which itself is a type of scanning probe microscopy. In nc-AFM a sharp probe is moved close (order of Angstroms ) to the surface under study, the probe is then raster scanned across the surface, the image is then ...
The Commission to Study the History of the Uprooting of Black Communities by Public Institutions of Higher Education in the Commonwealth met Monday to hear an update on the findings and work of ...
Membrane fluidity can be measured with electron spin resonance, fluorescence, atomic force microscopy-based force spectroscopy, or deuterium nuclear magnetic resonance spectroscopy. Electron spin resonance measurements involve observing spin probe behaviour in the membrane. Fluorescence experiments involve observing fluorescent probes ...
