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, ...

What Is Atomic Force Microscopy? Atomic force microscopy (AFM) is a powerful technique that enables surface ultrastructure visualization at molecular resolution. 1 Besides three-dimensional (3D) ...

A further development in atomic force microscopy now makes it possible to simultaneously image the height profile of nanometer-fine structures as well as the electric current and the frictional force ...

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 ...

Microscopes have long been scientists’ eyes into the unseen, revealing everything from bustling cells to viruses and nanoscale structures. However, even the most powerful optical microscopes have been ...

A standard single frequency AFM is comprised of a boron-doped silicon (Si) or silicon nitride (Si 3 N 4) cantilever with a length of a few micrometers and a single crystal diamond tip at the bottom of ...

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 ...

Inserting, removing or swapping individual atoms from the core of a molecule is a long-standing challenge in chemistry. This ...

Gerd Binnig shared The Kavli Prize in Nanoscience in 2016 for inventing the atomic force microscope. What transformative impact has this invention had on nanoscience? This podcast was produced for The ...

Every chemist's dream, to snap an atomic-scale picture of a chemical before and after it reacts, has now come true, thanks to a new technique developed by chemists and physicists at the University of ...

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 ...

(Nanowerk News) A molecule is a group of atoms bonded together. Molecules make up nearly everything around you – your skin, your chair, even your food. They vary in size, but are extremely small. You ...
