About this collection

Fluorescence was used for the first time as an analytical tool for the determination of various species and chemicals. Sensing based on fluorescence is one of the most effective methods for the detection of analytes since specially designed emitting probes allow high sensitivity and selectivity. Notably, materials that respond to external solicitations (physical or chemical) through variations in their fluorescence are today defined as chromogenic and/or fluorogenic.

This collection of articles, guest edited by Associate Editor Andrea Pucci (University of Pisa, Italy), covers a wide range of topics and reflects the broad spectrum of authors and readers of RSC Advances. It includes inspiring examples that together with the growing knowledge on the photophysics of chromophores, will stimulate the design of new effective tools for the development of sensors, probes and information displays.
