Interferometric scattering (iSCAT) microscopy, on the other hand, exploits back-scattered light and can detect structures as small as single proteins. As such, it can be used to "track" single ...

What is the Diffraction Limit? The diffraction limit is a fundamental barrier in optical microscopy that sets the minimum size of features that can be resolved using conventional light microscopes. It ...

A microscopic 'Christmas tree' is a seasonal look at a remarkable science project that found eerie comparisons between the ...
