Today we're looking at Atomic Force Microscopy! I built a "macro-AFM" to demonstrate the principles of an atomic force ...

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 ...

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 ...

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 pioneering high-speed atomic force microscope technology has now shed light on the structure and dynamics of some of life's most ubiquitous and inscrutable molecules - intrinsically disordered ...

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 ...

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 ...
