fluorescence Definition

fluo·res·cence (-əns)

noun

  1. the property of a substance, such as fluorite, of producing light while it is being acted upon by ultraviolet rays, X-rays, or other forms of radiant energy
  2. the production of such light
  3. light so produced

Etymology: < fluor(spar) + -escence

fluorescence Usage Examples

Converse of object

  • induce: By using a laser which excites the OH and induces fluorescence, he is able to measure the concentrations of the molecule.
  • emit: When injected as synthetic mRNA, its protein emits intense fluorescence in living embryos.

Noun used with modifier

  • chlorophyll: Ferry Box monitors phytoplankton levels by measuring chlorophyll fluorescence.
  • single-molecule: Our main focus of interest is in understanding the assembly and activation of membrane-bound proteins using single-molecule fluorescence.
  • two-photon: The example here shows 3-D images of vasculature in vivo, obtained using two-photon fluorescence excitation.
  • X-ray: X-ray fluorescence will be used to identify the metal rivets on one of the sheaths.
  • luminescence: The wedding cake of luminescence fluorescence to replace them phenomena with familiar concepts.
  • x-ray: To ensure that the composition of the alloy is correct, samples of the molten metal are routinely checked by x-ray fluorescence spectrometry.

Adjective modifier

  • laser-induced: The proportion of bound and free labeled peptides was determined using free-zone capillary electrophoresis and laser-induced fluorescence.
  • time-resolved: Fully automated neonatal screening utilizing time-resolved fluorescence is currently being developed.
  • intrinsic: The protein folding dynamics after mixing are measured by intrinsic tryptophan fluorescence excited by a UV lamp.
  • intense: When injected as synthetic mRNA, its protein emits intense fluorescence in living embryos.

Modifies a noun

  • microscopy: Advances in fluorescence microscopy have been central to this research.
  • spectra: The high signal to noise ratio in alumina fluorescence spectra is not achieved in the true Raman spectra developed by other types of ceramic.
  • spectroscopy: An illustrated description of X-ray fluorescence spectroscopy is available.
  • anisotropy: Work is currently being carried out to characterize the binding of the promoter site to HupR by gel filtration and fluorescence anisotropy.
  • spectrometry: This system may offer several advantages over the use of fluorescence spectrometry.
  • microscope: The optical port is C-mount threaded to accept optional adapters for direct coupling to various commercial fluorescence microscopes.

Preposition: in

  • hybridization: The aberration is readily detected by fluorescence in situ hybridization ( FISH ).
  • hybridisation: Chromosomal analysis can be carried out using fluorescence in situ hybridisation ( FISH ) technology, which gives a rapid result.
