pages.zeiss.comFluorescence microscopy can be based on autofluorescence or the addition of fluorescent dyes. It is mainly used in biology and medicine to observe structures and processes within a specimen. Introduction In 1852, the Irish physicist and mathematician Sir George Gabriel Stokes first observed fluorescence when sunlight, filtered

Spectroscopy: Principles, Theory, Techniques and Applications
mazams.weebly.comFluorescence spectroscopy uses higher energy photons to excite a sample, which will then emit lower energy photons. This technique has become popular for its biochemical and medical applications, and can be used for confocal microscopy, fluorescence resonance energy transfer, and fluorescence lifetime imaging. X-ray When X-rays of sufficient

images.novusbio.comFluorescence quantum yield is a measurement of emission efficiency and is calculated by the formula: ΦF = number of emitted photons/number of absorbed photons. The maximum quantum yield possible (ΦF = 1) signifies a 100% efficient fluorescence process. An example of a fluorochrome with high quantum yield is Alexa Fluor® 488 which has ΦF= 0.92.
