Fluorescentieindicators

Fluorescentieindicators are substances that exhibit fluorescence, a phenomenon where they absorb light at one wavelength and emit light at a longer wavelength. This property makes them useful in various scientific and technical applications as visual markers or sensors. When a fluorescentieindicator is exposed to excitation light, it absorbs the energy and then releases it as visible light, often in a different color. This emitted light can be detected and measured, providing information about the environment or the presence of specific substances.

The intensity and spectral characteristics of the fluorescence emitted by these indicators can be sensitive to changes in their surroundings, such as pH, ion concentration, temperature, or the presence of specific molecules. This sensitivity allows them to be used as probes to detect and quantify these changes. Common examples include fluorescein, rhodamine, and GFP (Green Fluorescent Protein). Fluorescentieindicators find applications in microscopy, flow cytometry, immunoassays, chemical analysis, and as dyes in various industrial processes. Their ability to provide sensitive and specific detection makes them invaluable tools across a wide range of scientific disciplines.
