Nuclear resonance fluorescence — (NRF) is a nuclear process in which a nucleus absorbs and emits high energy photons called gamma rays. NRF interactions typically take place above 1 MeV, and most NRF experiments target heavy nuclei such as uranium and thorium[1] Mode of… … Wikipedia
time-resolved fluorescence — Method to avoid interference by autofluorescence. Using an emitter fluorochrome that has slow decay characteristics coupled to the reagent of interest and temporally separating excitation and measurement, the signal can be arranged to derive… … Dictionary of molecular biology
Oxygen radical absorbance capacity — (ORAC) is a method of measuring antioxidant capacities in biological samples in vitro.[1][2] A wide variety of foods has been tested using this method, with certain spices, berries and legumes rated highly.[3] There exists no physiological proof… … Wikipedia
Kautsky effect — (also named fluorescence transient , fluorescence induction or fluorescence decay ) is a phenomenon consisting on a typical variation on the behavior of a plant fluorescence when is exposed to light. It was discovered in 1931 by H. Kautsky and A … Wikipedia
