Small Molecule Fluorescent Chemo sensors: A Review

A functional fluorescent molecule would be formed when a receptor molecule interacts with the proper analyte and exhibits fluorescence. This formed fluorophore can act as a chemosensors which perform the function like recognition of a particular analyte, detection and analysis. Besides being highly specific, this method also has a rapid response time, a low detection limit, and it is technically straightforward. In these devices, light is emitted by a material (fluorophore) after it is excited at a lower wavelength. In addition to being used as sensor devices, fluorescence-based sensors can also be used for monitoring metal ions. The different molecular entities presented here are well characterized for their sensitivity, selectivity, and low detection limits. So this method plays a significant role as an effective analytical technique.
