Colorimetric chemodosimeter based on diazonium-gold-nanoparticle complexes for sulfite ion detection in solution
A fast and simple colorimetric detection system for sulfite, based on diazonium–gold-nanoparticle(AuNP) complexation, has high selectivity and sensitivity in aqueous media. The positively charged diazonium has affinity for the AuNP surface due to an electrostatic effect, which prevents AuNPs from ag...
