Atomic Force Microscopy of Phytosterol Based Edible Oleogels

Gels, 2023
This work reviews the use of atomic force microscopy (AFM) as a tool to investigate oleogels of edible triglyceride oils. Specific attention is given to those oleogels based on phytosterols and their esters, a class of material the authors have studied ...

SNAREs: Could They be the Answer to an Energy Landscape Riddle in Exocytosis?

The Scientific World Journal, 2010
During exocytosis, chemical transmitters stored in secretory vesicles can be released upon fusion of these intracellular organelles to the plasma membrane. In this process, SNARE proteins that form a ternary core complex play a central role. This complex

High-precision atomic force microscopy with atomically-characterized tips

New Journal of Physics, 2020
Traditionally, atomic force microscopy (AFM) experiments are conducted at tip–sample distances where the tip strongly interacts with the surface. This increases the signal-to-noise ratio, but poses the problem of relaxations in both tip and sample that ...

Magnetic-Dielectric Cantilevers for Atomic Force Microscopy

Nanomaterials
Atomic force microscopy (AFM) is a technique that relies on detecting forces at the nanonewton scale. It involves using a cantilever with a tiny tip at one end. This tip interacts with the short- and long-range forces of material surfaces.

Energy dissipation in multifrequency atomic force microscopy

Beilstein Journal of Nanotechnology, 2014
The instantaneous displacement, velocity and acceleration of a cantilever tip impacting onto a graphite surface are reconstructed. The total dissipated energy and the dissipated energy per cycle of each excited flexural mode during the tip interaction is
