What is fluorescein used for?
It is widely used as a fluorescent tracer for many applications. Fluorescein is a fluorophore commonly used in microscopy, in a type of dye laser as the gain medium, in forensics and serology to detect latent blood stains, and in dye tracing. Fluorescein has an absorption maximum at 494 nm and emission maximum of 512 nm (in water).
Why is fluorescein used in plant science?
Plant science. Fluorescein has often been used to track water movement in groundwater to study water flow and observe areas of contamination or obstruction in these systems. The fluorescence that is created by the dye makes problem areas more visible and easily identified.
What is the derivative of fluorescein?
Many derivatives of fluorescein are known. Example. fluorescein isothiocyanate 1 , often abbreviated as FITC, features an isothiocyanate group ( −N=C=S) substituent. FITC reacts with the amine groups of many biologically relevant compounds including intracellular proteins to form a thiourea linkage.
How many ns does fluorescein have?
Also, the fluorescence lifetimes of the protonated and deprotonated forms of fluorescein are approximately 3 and 4 ns, which allows for pH determination from nonintensity based measurements. The lifetimes can be recovered using time-correlated single photon counting or phase-modulation fluorimetry .
How is fluorescein introduced to plants?
Fluorescein can be introduced to a plant's veins through the roots or a cut stem. The dye is able to be taken up into the plant the same way as water and moves from the roots to the top of the plant due to a transpirational pull.

Fluorescein was first synthesized by Adolf von Baeyer in 1871. It can be prepared from phthalic anhydride and resorcinol in the presence of zinc chloride via the Friedel-Crafts reaction .
Why do plants use fluorescent dye?
A similar concept can be applied to plants because the dye can make problems in plant vasculature more visible . 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.
Why do you need a fluorescein eye stain test?
A fluorescein eye stain test is usually ordered if your doctor suspects you have damage on your cornea or foreign objects in your eye. If you wear contact lenses, your doctor might do this test to see whether the contacts are damaging your cornea. During the test, a dark orange dye called fluorescein is placed onto the outer surface of your eye.
Can a fluorescein eye stain test be done on contact lenses?
Deeper scratches will take longer to heal and may cause scars. A fluorescein eye stain test can help your doctor detect corneal injuries, small foreign objects or particles in the eye, and abnormal tear production. The test may also help your doctor determine if your contact lenses are irritating your corneas or causing any damage.
How to do fluorescein staining?
Fluorescein staining of the cornea. Fluorescein staining of the cornea is performed by first placing a drop of sterile saline on a sterile fluorescein strip. The fluorescein is then placed in the inferior cul de sac of the eye by pulling down on the lower lid and gently touching the bulbar conjunctiva with the fluorescein strip.
Where is fluorescein placed in the eye?
The fluorescein is then placed in the inferior cul de sac of the eye by pulling down on the lower lid and gently touching the bulbar conjunctiva with the fluorescein strip.
How long does it take for fluorescein to diffuse?
Gently touch the inside of the lower eyelid with the moistened strip without touching cornea. Allow fluorescein dye to diffuse approximately 30 seconds. Scan the cornea or bulbar conjunctiva for areas of dye uptake that appear bright green with blue light (slit lamp)
What does a yellow glow on a lens mean?
A yellow-green glow indicates the presence of fluorescein and therefore clearance between the lens and cornea. A deep blue or black area indicates the absence of fluorescein and therefore the lens is touching the cornea.
