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, ...

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 ...

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 ...

Cool operator: the Saharan silver ant Cataglyphis bombycina. (Courtesy: P Landmann) A species of desert-dwelling ant is able to tolerate temperatures exceeding 50 °C because its body hairs act like ...

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 ...

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 ...
