Total internal reflection fluorescence 


Total internal reflection fluorescence search for term

A total internal reflection fluorescence imaging device produces an evanescent wave — that is, a near-field stationary excitation wave with an intensity that decreases exponentially away from the surface. This wave propagates across a boundary surface, such as a glass slide, resulting in the excitation of fluorescent molecules near (<200 nm) or at the surface and the subsequent collection of their emission signals by a detector.
