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 ...

The DeltaVision OMX V4 enables Total Internal Reflection Fluorescence Microscopy (TIRF). This technique uses an evanescent wave to selectively excite fluorophores that are close to the coverslip. This ...

Light that is reflected back from the edge of the medium it is traveling through. When light rays travel at an angle greater than the "critical" angle, which is determined by the medium, the light ...

The AR glasses optical waveguide system consists of a display and an optical lens that uses TIR principles to transport light ...

Proceedings of the National Academy of Sciences of the United States of America, Vol. 104, No. 10 (Mar. 6, 2007), pp. 4212-4217 (6 pages) Transmitters such as glutamate and ATP are released from brain ...

SANTA CRUZ, CA--Researchers at the University of California, Santa Cruz, have reported the first demonstration of integrated optical waveguides with liquid cores, a technology that enables light ...

When a ray of light that is travelling through a piece of glass strikes the interface between the glass and the air, it changes direction according to Snell’s law. If the angle of incidence is less ...

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, ...
