 Nanovid microscopy

Nanovid microscopy, from “nanometer video-enhanced microscopy”, is a microscopic technique aimed at visualizing colloidal gold particles of 20–40 nm diameter (nanogold, immunogold) as dynamic markers at the light-microscopic level.The nanogold particles as such are smaller than the diffraction limit of light, but can be visualized by using video-enhanced differential interference contrast (VEDIC).
