Fluorescence recovery after photobleaching (FRAP) is a pivotal technique for investigating the dynamics of biomolecules within live cells. By selectively photobleaching a small region and monitoring ...
Fluorescence is the property of some atoms and molecules to absorb light at a particular wavelength and to subsequently emit light of longer wavelength after a brief interval, termed the fluorescence lifetime.
Divalent manganese, in concentrations of up to several percent, is responsible for the red or orange fluorescence of calcite, the green fluorescence of willemite, the yellow fluorescence of esperite, and the orange fluorescence of wollastonite and clinohedrite.
Fluorescence is a phenomenon where certain materials rapidly (around 10 -8 seconds) emit light when they are exposed to specific types of electromagnetic radiation, typically ultraviolet (UV) light.
Fluorescence, a type of luminescence, occurs in gas, liquid or solid chemical systems. Fluorescence is brought about by absorption of photons in the singlet ground state promoted to a singlet excited state.
Explore how fluorescence works—the rapid light emission driven by electron transitions—and its vital role in lighting, imaging, and forensics.
Fluorescence, emission of electromagnetic radiation, usually visible light, caused by excitation of atoms in a material, which then reemit almost immediately (within about 10−8 seconds).
Fluorescence is the result of a 3-stage process that occurs in certain molecules (e.g., polyaromatic hydrocarbons) called fluorophores.
Fluorescence analysis can be used to follow separation processes of plant and animal chemical components and tissues in food production because of naturally present fluorescence markers (autofluorescence or primary fluorescence).
Fluorescence was first encountered in optical microscopy during the early part of the twentieth century by several notable scientists, including August Köhler and Carl Reichert, who initially reported that fluorescence was a nuisance in ultraviolet microscopy.
