Fluorescence spectrophotometer is an instrument used to scan the fluorescence spectrum emitted by liquid-phase fluorescent markers. It can provide many physical parameters including excitation spectrum, emission spectrum, fluorescence intensity, quantum yield, fluorescence lifetime, fluorescence polarization, etc., reflecting the bonding and structure of molecules from various angles. General quantitative analysis can be done, and the conformational changes of molecules in various environments can be inferred to clarify the relationship between molecular structure and function.
Fluorescence spectroscopy is used in, among others, biochemical, medical, and chemical research fields for analyzing organic compounds. There has also been a report of its use in differentiating malignant skin tumors from benign. Additionally, Fluorescence spectroscopy can be adapted to the microscopic level using microfluorimetry. In analytical chemistry, fluorescence detectors are used with HPLC. In the field of water research, fluorescence spectroscopy can be used to monitor water quality by detecting organic pollutants. Recent advances in computer science and machine learning have even enabled detection of bacterial contaminaton of water.
