Polynomial force approximations and multifrequency atomic force microscopy

Beilstein Journal of Nanotechnology, 2013
We present polynomial force reconstruction from experimental intermodulation atomic force microscopy (ImAFM) data. We study the tip–surface force during a slow surface approach and compare the results with amplitude-dependence force spectroscopy (ADFS ...

Atomic Force Microscopy: An Introduction

, 2017
Imaging of nano-sized particles and sample features is crucial in a variety of research fields. For instance in biological sciences, where it is paramount to investigate structures at the single particle level. Often two-dimensional images are not sufficient and further information such as topography and mechanical properties are required. Furthermore,

Force Sensing on Cells and Tissues by Atomic Force Microscopy

Sensors, 2022
Biosensors are aimed at detecting tiny physical and chemical stimuli in biological systems. Physical forces are ubiquitous, being implied in all cellular processes, including cell adhesion, migration, and differentiation.

Piezoresistive sensors for atomic force microscopy

Journal of Telecommunications and Information Technology, 2001
An important element in microelectronics is the comparison of the modelling and measurements results of the real semiconductor devices. Our paper describes the final results of numerical simulation of a micromechanical process sequence of the atomic ...

Combined Traction Force–Atomic Force Microscopy Measurements of Neuronal Cells

Biomimetics, 2022
In the course of the development of the nervous system, neuronal cells extend (grow) axons, which navigate over distances of the order of many cell diameters to reach target dendrites from other neurons and establish neuronal circuits.

Morphology and Nanomechanics of Sensory Neurons Growth Cones following Peripheral Nerve Injury [PDF]

, 2012
A prior peripheral nerve injury in vivo, promotes a rapid elongated mode of sensory neurons neurite regrowth in vitro. This in vitro model of conditioned axotomy allows analysis of the cellular and molecular mechanisms leading to an improved neurite re ...

Rheology of passive and adhesion-activated neutrophils probed by Atomic Force Microscopy [PDF]

, 2006
The rheology of neutrophils in their passive and activated states plays a key role in determining their function in response to inflammatory stimuli. Atomic force microscopy was used to study neutrophil rheology by measuring the complex shear modulus G ...

Hyperosmotic stress induces PARP1‐mediated HPF1‐dependent mono(ADP‐ribosyl)ation

FEBS Letters, EarlyView.
Sorbitol‐induced hyperosmotic stress rapidly induces reversible mono(ADP‐ribosyl)ation (MARylation) on PARP1 without the signs of genotoxic signaling. We show that PARP1 autoMARylation is HPF1 dependent and forms hydroxylamine‐resistant O‐glycosidic linkages.
