Fluorescent minerals emit visible light when exposed to ultraviolet. Fluorescent marine organisms Fluorescent clothes used in black light theater production, Prague. Fluorescence is one of two kinds of photoluminescence, the emission of light by a substance that has absorbed light or other electromagnetic radiation.
Distribution of fluorescent proteins in animals. The hippocampus of a mouse imaged via fluorescence microscopy. Biofluorescent emission spectra from amphibians Example uses of fluorescent proteins for imaging in the life sciences. Fluorescence is used in the life sciences generally as a non-destructive way of tracking or analysing biological ...
Atomic Fluorescence Spectroscopy (AFS) techniques are useful in other kinds of analysis/measurement of a compound present in air or water, or other media, such as CVAFS which is used for heavy metals detection, such as mercury. Fluorescence can also be used to redirect photons, see fluorescent solar collector.
Alternatively the intrinsic fluorescence of a sample (i.e., autofluorescence) can be used. [1] In the life sciences fluorescence microscopy is a powerful tool which allows the specific and sensitive staining of a specimen in order to detect the distribution of proteins or other molecules of interest. As a result, there is a diverse range of ...
Fluorescence is the emission of light by a molecule or an atom that has absorbed light or other electromagnetic radiation. In most cases, the emitted light has a longer wavelength , and therefore a lower photon energy , than the absorbed radiation.
X-ray fluorescence (XRF) is the emission of characteristic "secondary" (or fluorescent) X-rays from a material that has been excited by being bombarded with high-energy X-rays or gamma rays.
Fluorescence correlation spectroscopy (FCS) is an analysis technique that observes the fluctuation of fluorescence intensity. This analysis is a component of many fluorescence imaging machines and improvements in spatial resolution could improve the sensitivity and range.
In plant science, fluorescein, and other fluorescent dyes, have been used to monitor and study plant vasculature, particularly the xylem, which is the main water transportation pathway in plants. This is because fluorescein is xylem-mobile and unable to cross plasma membranes , making it particularly useful in tracking water movement through ...
