Total internal reflection microscopy is a light microscopy technique that relies on total internal reflection of illumination light to generate an evanescent wave that extends less than 200 nm from ...

In TIRF microscopy, fluorescent molecules are in a sample in an aqueous environment that is near a solid with a high refractive index, usually a glass coverslip. At what is called the critical angle, ...

Total internal reflection–fluorescence correlation spectroscopy (TIR-FCS) is an emerging technique that is used to measure events at or near an interface, including local fluorophore concentrations, ...

TIRF is a microscopy technique that is used to image fluorescent molecules, such as green fluorescent protein (GFP) and fluorochromes, in liquids that are adjacent to a solid with a high refractive ...

Refraction close refractionProcess by which a wave changes speed and sometimes direction upon entering a denser or less dense medium, eg a light ray changes direction when refracted by a lens. from a ...

When we first saw "interactive touch-screen display" in the tips jar, it made us think of playing MegaTouch 9000 at a seedy bar and we were about to toss it in the ol' recycling bin. Then we decided ...

The body hairs of the Saharan silver ant cause total internal reflection of light to make the ants almost ten times more reflective, preventing overheating and yielding their silver sheen, according ...
