Atomic force microscopy reveals three distinct dynamic states in individual polymer chain segments on surfaces, challenging ...

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 ...

First invented in 1985 by IBM in Zurich, Atomic Force Microscopy (AFM) is a scanning probe technique for imaging. It involves a nanoscopic tip attached to a microscopic, flexible cantilever, which is ...

Anyone who has ever taken the time to critically examine a walnut knows that a two-dimensional photograph fails in many respects to truly convey the unique features--the nicks, crannies, valleys, and ...

Kyushu University researchers have directly observed, for the first time, how individual polymers—chain-like molecules—behave when in contact with solid surfaces. Published in the Journal of the ...

New model extracts stiffness and fluidity from AFM data in minutes, enabling fast, accurate mechanical characterization of living cells at single-cell resolution. (Nanowerk Spotlight) Cells are not ...

Atomic force microscopy (AFM) has evolved into an indispensable tool for nanoscale imaging and fabrication, enabling both high-resolution surface characterisation and precise nanomachining. By ...

Key TakeawaysBerkeley Lab scientists developed a new way to determine atomic structures from nanocrystals previously ...

Using atomic force microscopy, the researchers measured nanometric changes in height along different segments of a single polymer molecule. Through careful mathematical processing of these ...

In July 1985, three physicists—Gerd Binnig of the IBM Zurich Research Laboratory, Christoph Gerber of the University of Basel, and Calvin Quate of Stanford University—puzzled over a problem while ...

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, ...
