Force Spectroscopy in Studying Infection [PDF]

, 2016
Biophysical force spectroscopy tools - for example optical tweezers, magnetic tweezers, atomic force microscopy, - have been used to study elastic, mechanical, conformational and dynamic properties of single biological specimens from single proteins to whole cells to reveal information not accessible by ensemble average methods such as X-ray ...

Analysis of membrane structure of the inner ear motor protein prestin by force spectroscopy

Journal of Biomechanical Science and Engineering, 2021
The high sensitivity of mammalian hearing is achieved by cochlear amplification. The basis of this amplification is the motility of outer hair cells (OHCs), which are sensory cells in the inner ear.

Theory of rapid force spectroscopy [PDF]

Nature Communications, 2014
AbstractIn dynamic force spectroscopy, single (bio-)molecular bonds are actively broken to assess their range and strength. At low loading rates, the experimentally measured statistical distributions of rupture forces can be analysed using Kramers’ theory of spontaneous unbinding.

Modification of a single-molecule AFM probe with highly defined surface functionality

Beilstein Journal of Nanotechnology, 2014
Single-molecule force spectroscopy with an atomic force microscope has been widely used to study inter- and intramolecular interactions. To obtain data consistent with single molecular events, a well-defined method is critical to limit the number of ...

Atomic-Site-Specific Analysis on Out-of-Plane Elasticity of Convexly Curved Graphene and Its Relationship to s p 2 to s p 3 Re-Hybridization

Crystals, 2018
The geometry of two-dimensional crystalline membranes is of interest given its unique synergistic interplay with their mechanical, chemical, and electronic properties. For one-atom-thick graphene, these properties can be substantially modified by bending

On a three-body confinement force in hadron spectroscopy [PDF]

, 2001
Recently it has been argued that a three-body colour confinement interaction can affect the stability condition of a three-quark system and the spectrum of a tetraquark described by any constituent quark model.

Diamond Colloidal Probe Force Spectroscopy [PDF]

Analytical Chemistry, 2019
Diamond is a highly attractive coating material as it is characterized by a wide optical transparency window, a high thermal conductivity, and an extraordinary robustness due to its mechanical properties and its chemical inertness. In particular, the latter has aroused a great deal of interest for scanning probe microscopy applications in recent years.

Relevance of Host Cell Surface Glycan Structure for Cell Specificity of Influenza A Viruses

Viruses, 2023
Influenza A viruses (IAVs) initiate infection via binding of the viral hemagglutinin (HA) to sialylated glycans on host cells. HA’s receptor specificity towards individual glycans is well studied and clearly critical for virus infection, but the ...

Noncontact lateral-force gradient measurement on Si(111)-7×7 surface with small-amplitude off-resonance atomic force microscopy [PDF]

, 2009
In this work, the authors report on a quantitative investigation of lateral-force gradient and lateral force between a tungsten tip and Si(111)-(7×7) surface using combined noncontact lateral-force microscopy and scanning tunneling microscopy ...

Force Spectroscopy of Single Biomolecules [PDF]

ChemPhysChem, 2002
Many processes in the body are effected and regulated by highly specialized protein molecules: These molecules certainly deserve the name "biochemical nanomachines". Recent progress in single-molecule experiments and corresponding simulations with supercomputers enable us to watch these "nanomachines" at work, revealing a host of astounding mechanisms.
