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 ...

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 way to investigate the surface features of some materials. It works by “feeling” or “touching” the surface with an extremely small probe. This provides a ...

For anyone that’s fiddled around with a magnifying glass, it’s pretty easy to understand how optical microscopes work. And as microscopes are just an elaboration on a simple hand lens, so too are ...

A new perspectives article focuses on different ways to study the mouthfeel of food using atomic force microscopy to better understand the biophysical mechanisms that contribute to taste sensations in ...

Atomic force microscopy is a powerful technique that has been widely used in materials research, nano-imaging, and bioimaging. It is a topographical metrology approach that is commonly utilized in ...

PFM is based on the converse piezoelectric effect, where an applied electric field induces mechanical strain in piezoelectric materials. In PFM, an AC voltage is applied between a conductive atomic ...

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 ...

Invented in 1986 atomic force microscopy (AFM) has become a valuable tool for life scientists, offering the ability to image aqueous biological samples, like membranes, at nanometer resolution. The ...
