The Introductction of ​Fluorescein Sodium:


Fluorescein is a synthetic organic compound with a dark orange/red powder appearance. It is soluble in ethanol and slightly soluble in water. Under blue light or ultraviolet light, it emits green fluorescence.

Fluorescein sodium is a disodium salt of fluorescein and a noted pH sensitive fluorophore. Fluorescein sodium salt has been utilized in studies as a drug model, as a penetrating dye and also as a fluorescein tracer.
Fluorescein sodium salt has also been used in vitro to quantify root dentin demineralization. Additional reported uses include microscopy, as a gain medium in dye laser use and to detect latent blood stains in vitro.


The Application & Function of Fluorescein Sodium:


1. Sodium fluorescein is the first fluorescent dye used for water tracing purposes
2. Used for applanation intraocular pressure measurement
