AN135-Rev A0-Quantitative-Imaging-Living-Biological-Samples-PeakForceQNM-(HiRes).pdf This article summarizes work that has conducted over the past year on living (and thus soft) samples by using Peak Force QNM. It focuses on silicified organisms, bacteria, and eukaryiotic cells. The Note also proposes...

It is now well established that measuring ex vivo the mechanical properties of living cells can be a good indicator of the health of the organism from which they were extracted. Atomic force microscopy (AFM) is a powerful investigation and diagnostic tool, especially in force mode. Nevertheless, force...

Veeco recently released a new Perfusing Stage Incubator accessory for the BioScope Catalyst. It enables long term maintenance of cells in situ on the BioScope Catalyst. Please see the article just published in Microscopy and Analysis for more details ( Link here ). Abstract Atomic force microscopy has...

Alexandre Berquand, Applications Scientist at Veeco, in partnership with the Pr. Petra Kioshis Group at the Hochschule Mannheim, have published a paper in the March issue of Microscopy Today titled: Analysis of Cytoskeleton-Destabilizing Agents by Optimized Optical Navigation and AFM Force Measurements...

Mechanical properties of cells are determined by the dynamic behavior of the cytoskeleton and physical interactions with the environment. The cytoskeleton, composed of actin filaments, intermediate filaments, and microtubules, is vital for numerous key cellular processes, such as cell division, vesicle...

Atomic force microscopy (AFM) has opened exciting new avenues in microbiology and biophysics for probing microbial cells. The unprecedented capabilities of AFM can be summarized as follows: i) imaging surface topography with nanometer lateral resolution and under physiological conditions; ii) measuring...

In the following study, we demonstrate the power of combining atomic force microscopy AFM and fluorescence microscopy techniques to probe real-time, in-situ effects of two highly specific drugs that are able to disrupt different cytoskeleton networks inside living cells. Using Veeco Multiple Image Registration...

There is great interest in unraveling action mechanisms of key enzymes in biological processes. In many cases, insight on such molecular events can be derived from conventional biophysical analyses of isolated enzymes and their substrates or protein partners. For example, members of the matrix metalloproteinases...
