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 ...

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 ...

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 ...

Lab-grown muscle stem cells from mice mimic the formation of muscle fibers in vivo. A series of rodent experiments showed that even with abundant food and water, personal space is essential to prevent ...
