Our bodies comprise different tissues and organs, which are composed of many cells that must adhere to form functional higher order structures. This adherence is facilitated by specialized proteins ...

Invented 30 years ago, the atomic force microscope has been a major driver of nanotechnology, ranging from atomic-scale imaging to its latest applications in manipulating individual molecules, ...

Analyzing structures and physicochemical properties of biomolecules is a major field of research in biotechnology. The four major types of biological macromolecules namely, carbohydrate, proteins, ...

In nanotechnology and molecular biology, researchers are often severely limited by the inability to observe atoms and molecules in three dimensions. Proteins, for instance, fold into complex patterns ...

Atomic force microscopy (AFM) and infrared (IR) spectroscopy have emerged as complementary techniques that enable the precise characterisation of materials at the nanoscale. AFM provides ...

Fast-scanning atomic force microscopy imaging of the molecule at two different time points shows positional shifts along the polymer chain on the left. On the right, the molecular structure of PEG ...

When it comes to analyzing living cells, challenging biological samples and thick, multilayer tissue samples require purposefully designed instrumentation. BioAFMs are ideal when it comes to these ...

IBM's atomic force microscope now can distinguish charged gold atoms from neutral ones. Big Blue hopes that will help with nanocomputing and solar energy research. Stephen Shankland worked at CNET ...

In what's being hailed as an important first for chemistry, an international team of scientists has developed a new technology that can selectively rearrange atomic bonds within a single molecule. The ...

Leo Gross is a physicist who has devoted his career to studying the fundamental secrets of chemistry—that is, how atoms and molecules behave and interact with one another. As leader of IBM’s atom and ...

(Nanowerk News) Take a photo with your phone and you might see wonderful details—leaves on a tree, strands of hair blowing in the wind. The width of that strand of hair is 100,000 nanometers wide. The ...
