A research team has developed a technology that distinguishes lung cancer gene mutations solely by measuring the "stiffness" of exosomes—tiny particles released from cancer cells in the ...

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) ...

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 ...

Microscopy continues to transform the life sciences. Here are five recent breakthroughs made possible by the technique.

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 ...

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 ...

The Nature Index 2025 Research Leaders — previously known as Annual Tables — reveal the leading institutions and countries/territories in the natural and health sciences, according to their output in ...

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 ...

Scientists at the Department of Energy's Oak Ridge National Laboratory have reimagined the capabilities of atomic force microscopy, or AFM, transforming it from a tool for imaging nanoscale features ...

Atomic force microscopy (AFM) is a high-resolution imaging technique that generates 3D images of sample surfaces and characterizes their nanomechanical properties. AFM can be used for several ...
