Fluorescent Labels in Microscopy
Description
Fluorescent labels make tiny parts of a sample easier to see with a light microscope. Fluorescence microscopy combines normal magnification with fluorescence, which is the absorbance and emission of a small range of light wavelengths by a fluorophore. A fluorophore is a fluorescent molecule that gives off light after it abso...

Transcript
Fluorescence is a phenomenon that takes place when a substance absorbs light at a given wavelength and emits light at another wavelength. Fluorescence occurs as an electron, which has been excited to a higher, and more unstable energy state, relaxes to its ground state and gives off a photon of light. The light that is respon...
