A new method for obtaining model-free viscoelastic material properties from atomic force microscopy experiments using discrete integral transform techniques

Beilstein Journal of Nanotechnology, 2021
Viscoelastic characterization of materials at the micro- and the nanoscale is commonly performed with the aid of force–distance relationships acquired using atomic force microscopy (AFM).

Statistical Study of Low-Intensity Single-Molecule Recognition Events Using DeepTip^TM Probes: Application to the Pru p 3-Phytosphingosine System

Biomimetics, 2023
The interaction between the plant lipid transfer protein Pru p 3 and phytosphingosine was assessed using an atomic force microscope. Phytosphingosine was covalently immobilized on DeepTipTM probes and Pru p 3 on MicroDeckTM functionalized substrates ...

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 ...

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.

Concurrent Atomic Force Spectroscopy [PDF]

Communications Physics, 2018
ABSTRACT Force-spectroscopy by Atomic Force Microscopy (AFM) is the technique of choice to measure mechanical properties of molecules, cells, tissues and materials at the nano and micro scales. However, unavoidable calibration errors of AFM probes make it cumbersome to quantify modulation of mechanics.

Quantitative investigation of calcimimetic R568 on beta cell adhesion and mechanics using AFM single-cell force spectroscopy [PDF]

, 2014
In this study we use a novel approach to quantitatively investigate mechanical and interfacial properties of clonal β-cells using AFM-Single Cell Force Spectroscopy (SCFS). MIN6 cells were incubated for 48hrs with 0.5mM Ca2+ ± the calcimimetic R568 (1μM).
