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, ...

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 ...

Physics and Python stuff. Most of the videos here are either adapted from class lectures or solving physics problems. I really like to use numerical calculations without all the fancy programming ...

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 ...
