Quimiossensores cromogênicos e fluorogênicos para a detecção de analitos aniônicos

The detection of anionic species is a field which is currently attracting increasing interest. Research is carried out not only to gain a better understanding of biological events that anions participate in, but also to ascertain the potential contribution of the anionic chemosensors to the qualitative and quantitative analysis of species of interest in the areas of industry, medicine, the environment, and chemistry. This review summarizes several aspects related to the main strategies used in anion sensing. Each strategy discussed is illustrated with its potential applications citing recent examples. The prospects for their use in several areas are also described.
