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, ...

Understand the physics behind total internal reflection and why light can become completely trapped inside a medium. This video explains the conditions required for total internal reflection, the role ...

Total internal reflection microscopy is a light microscopy technique that relies on total internal reflection of illumination light to generate an evanescent wave that extends less than 200 nm from ...

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 ...

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 ...
