Natriumfluoresseiiniä

Natriumfluoresseiiniä, also known as sodium fluorescein, is a water-soluble dye with the chemical formula C20H10Na2O5. It is a fluorescent compound, meaning it emits light when exposed to ultraviolet or visible light. This property makes it useful in various diagnostic and scientific applications.

In medicine, sodium fluorescein is used as a diagnostic dye. Ophthalmic uses include examining the eye for injuries or defects in the cornea and retina. When injected intravenously, it can be used to detect abnormalities in blood vessels, such as leaks in the retina due to diabetic retinopathy or macular degeneration. Its passage through the bloodstream can also be visualized, aiding in the study of blood flow.

Beyond medical diagnostics, sodium fluorescein finds applications in research. It is employed as a tracer in hydrology to study water flow patterns in rivers, groundwater, and sewage systems. Its fluorescence allows for easy detection and quantification in water samples. In biology, it can be used to label cells or tissues for microscopic examination, helping to understand cellular processes or locate specific structures. The dye is typically administered in solution and its bright green fluorescence under appropriate lighting conditions is its key characteristic for detection.
