Atomic Force Microscopy News and Research

RSS

Atomic force microscopy is a type of scanning probe microscopy used to image the surface of a substance, but at an atomic level. It can map the surface structure of different substances to understand how different structures interact with each other. This is done using a cantilever, which is similar to a vinyl record needle.

TUM biophysicists map changes in energy landscape of zipper-like protein molecule

Biophysicists at TUM, the Technische Universitaet Muenchen, have published the results of single-molecule experiments that bring a higher-resolution tool to the study of protein folding. How proteins arrive at the three-dimensional shapes that determine their essential functions - or cause grave diseases when folding goes wrong - is considered one of the most important and least understood questions in the biological and medical sciences.

I-STEM team succeeds in recreating a whole epidermis from hES cells

Stem cell research is making great strides. This is yet again illustrated by a study carried out by the I-STEM Institute (I-STEM/ Inserm UEVE U861/AFM), published in the Lancet on 21 November 2009. The I-STEM team, directed by Marc Peschanski has just succeeded in recreating a whole epidermis from human embryonic stem cells.

Protein unfolding key to understanding blood clot mechanics

Fibrin, the chief ingredient of blood clots, is a remarkably versatile polymer. On one hand, it forms a network of fibers -- a blood clot -- that stems the loss of blood at an injury site while remaining pliable and flexible. On the other hand, fibrin provides a scaffold for thrombi, clots that block blood vessels and cause tissue damage, leading to myocardial infarction, ischemic stroke, and other cardiovascular diseases. How does fibrin manage to be so strong and yet so extensible under the stresses of healing and blood flow?

WHO, UNICEF say vitamin A, deworming interventions safe, in response to alleged deaths, sickness in Bangladesh

The WHO and UNICEF on Tuesday said that vitamin A supplements and deworming tablets are safe, after two deaths and the "sickness of hundreds" were alleged among the children who received the interventions during a nationwide campaign in Bangladesh, Bernama.com reports (Bernama.com, 6/9).

Examining the infinitesimal - new approach to microscopy

A new approach to microscopy is opening up the wonders of the molecular world, allowing researchers to examine organic molecules and delicate crystals as they grow, atom by atom. Dr Andrew Humhpris, co-founder of the original technology and now Chief Technology Officer of Infinitesima, explains how this University spin-out has turned into a leading-edge company.

How chemicals present in cranberries prevent urinary tract infections

Chemicals present in cranberries - and not the acidity of cranberry juice, as previously thought - prevent infection-causing bacteria from attaching to the cells that line the urinary tract, as documented in a report published in Journal of Medicinal Food.

Researchers look at processes asbestos fibers use to trigger cancer in human cells

Ohio State University scientists believe they are the first in the world to study the molecular underpinnings of cancer by probing individual bonds between an asbestos fiber and human cells.

Alpha-catenin protein provokes healthy cell bonding

In human relationships, a certain "spark" often governs whether we prefer one person more than another, and critical first impressions can occur within seconds. A team lead by Johns Hopkins researchers has found that cell-to-cell "friendships" operate in much the same way and that dysfunctional bonding is linked to the spread of cancer.

Next-generation nanomedicine

In an article featured on the cover of the March issue of Nature Nanotechnology, Mauro Ferrari, Ph.D., of The University of Texas Health Science Center at Houston, presented a proof-of-concept study on a new multistage delivery system (MDS) for imaging and therapeutic applications. This discovery could go a long way toward making injectable drugs more effective.
