“There is no branch of detective science that is so important and so much neglected as the art of tracing footsteps,” says the fictional detective Sherlock Holmes. Now, UK researchers have developed a ...

Such a thick layer can be observed when the liquid is held within a transparent container and the observer is looking at the top most portion of the liquid from the sides of the transparent container.

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 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 ...

Science presenter Jon Chase explains total internal reflection. He demonstrates how total internal reflection can make a coin disappear inside a glass of water and bend a laser beam. The second ...

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 ...

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 ...
