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.

Collagen VI protects brain cells against amyloid-beta proteins

Scientists from the Gladstone Institute of Neurological Disease (GIND), UCSF, and Stanford have discovered that a certain type of collagen, collagen VI, protects brain cells against amyloid-beta proteins, which are widely thought to cause Alzheimer's disease (AD).

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.

Direct sequencing of single RNA strands with tip-enhanced Raman spectroscopy

The genetic alphabet contains four letters. Although our cells can readily decipher our genetic molecules, it isn't so easy for us to read a DNA sequence in the laboratory. Scientists require complex, highly sophisticated analytical techniques to crack individual DNA codes.
