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, ...

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 ...

Force spectroscopy relies on the precise measurement of forces acting on a probe as it interacts with a sample. The key principles of force spectroscopy include: AFM-based force spectroscopy is the ...

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 ...

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 ...

Atomic force microscopy (AFM) is a method of topographical measurement, wherein a fine probe is raster scanned over a material, and the minute variation in probe height is interpreted by laser ...

(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 ...

Christoph Gerber, who co-invented the atomic force microscope, tells Matthew Chalmers how the AFM came about 30 years ago and why it continues to shape research at the nanoscale Nano-vision Christoph ...
