Macrophages drive key immune processes including inflammation, tissue repair, and tumorigenesis via distinct polarization ...

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 ...

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 ...

In order to increase our understanding of structural dynamics of biomolecules at the single-molecule level, they would need to be captured at the sub-nanometer scale and in physiologically relevant ...

Today we're looking at Atomic Force Microscopy! I built a "macro-AFM" to demonstrate the principles of an atomic force microscope, then we look at a real AFM (an nGauge AFM from ICSPI) and do a few ...

Scientists have developed a computational technique that greatly increases the resolution of atomic force microscopy, a specialized type of microscope that 'feels' the atoms at a surface. The method ...

With atomic force microscopy, tiny structures can be imaged. But usually there is a trade of: In order to create pictures quickly, very stiff materials have to be used in the microscope, but they can ...

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 ...
