All Uses of Fluorescein

1. Medical Diagnostics & Ophthalmology

• Corneal Abrasions & Fit Testing: Gold standard in fluorescein eye strips; stains damaged corneal epithelium bright green under cobalt blue light.
• Angiography: Intravenous fluorescein sodium maps retinal blood vessels in real-time (fundus fluorescein angiography).
• Surgical Guidance: Highlights sentinel lymph nodes in cancer staging.

2. Leak & Flow Detection

• Plumbing & HVAC: Traces leaks in pipes, radiators, and roofs (glows under UV).
• Hydrology: Tracks groundwater flow, river connectivity, and pollution dispersion.
• Aerospace: Detects micro-cracks in fuel lines and hydraulic systems.

3. Scientific Research & Forensics

• Cell Biology: Labels antibodies, proteins, and DNA in fluorescence microscopy (FITC conjugate).
• Forensics: Reveals latent fingerprints and bodily fluids at crime scenes under alternate light sources.
• Oceanography: Dye-release studies to model currents and dispersion.

4. Industrial & Safety Applications

• Non-Destructive Testing (NDT): Penetrant dye in fluorescent penetrant inspection (FPI) for surface defects in metals.
• Search & Rescue: Aerial drops create glowing markers visible for miles (e.g., sea dye markers).
• Textile & Paper: Fluorescent whitening agent (historical use).

5. Art, Entertainment & Education

• Blacklight Art & Raves: Core pigment in UV-reactive paints, inks, and body paint.
• Laser Shows: Amplifies green laser beams in fog for volumetric effects.
• Chemistry Demos: Classic fluorescence vs. phosphorescence experiment with UV lamps.

6. Environmental & Specialty Uses

• Water Treatment: Monitors filtration efficiency and membrane integrity.
• Antifreeze Tracer: Added to coolant to detect engine leaks (glows under UV).
• pH Indicator: Shifts color in highly acidic/basic solutions (though less common).
