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 ...

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, ...

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 ...

The Wolfson Bioimaging Facility provides total internal reflection fluorescence microscopy (TIRF) with its multi-laser, dual-camera Olympus/Abbelight SAFe360 system which also offers single molecule ...

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 ...

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 ...

Bound states in the continuum (BICs) are a special class of resonant states. Although they have the same momentum and energy as the propagating modes in free space, yet they are not coupled to the ...
