Fluorescence Spectroscopy

What is Fluorescence Spectroscopy?

Fluorescence Spectroscopy is a highly sensitive analytical technique that measures light emitted by fluorescent molecules after excitation by a specific wavelength. When a fluorophore absorbs energy, it emits light at a longer wavelength—producing an emission spectrum that reveals molecular structure, interactions, concentration, and environmental effects.

This technique is widely used for trace-level detection, biological labeling, polymer characterization, and nanomaterial tracking, making it a powerful tool for research and quality evaluation.

Use of Fluorescence Spectroscopy

Fluorescence Spectroscopy allows researchers to:
• Detect and quantify fluorescent molecules, dyes, proteins, and tags
• Measure molecular interactions (binding, quenching, conformational changes)
• Monitor degradation, oxidation, or chemical modifications
• Evaluate fluorescent probes in polymers, coatings, and hydrogels
• Analyze biological fluorophores in cells, tissues, and biofilms
• Track drug penetration, nanoparticles, or functionalized materials

Applications of Fluorescence Spectroscopy

Biological & Pharmaceutical: protein assays, biomolecule tracking, drug-binding studies
Biomaterials & Tissue Engineering: fluorescent labeling of scaffolds and hydrogels
Nanotechnology: quantum dot characterization, nanoparticle uptake analysis
Environmental & Chemical Testing: detection of pollutants and organics
Polymers & Coatings: fluorescent additives, crosslinking, diffusion studies
