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 ...

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 ...

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, ...

Doing it yourself may not get you the most precise lab equipment in the world, but it gets you a hands-on appreciation of the techniques that just can’t be beat. Today’s example of this adage: [Stoppi ...

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 ...

At its core, SPM operates on the principle of measuring interactions between a sharp probe and the surface of a material. As the probe scans across the surface, it detects variations in physical ...

AFM differs significantly from traditional microscopy techniques as it does not project light or electrons on the sample's surface to create its image. Instead, AFM utilizes a sharp probe while ...
