Copper-enhanced fluorescence: a novel platform for the sensing of hydrogen peroxide

Abstract

The small molecule salicylaldehyde was used to achieve copper-enhanced fluorescence. The fluorescence was investigated under various physicochemical conditions. Such fluorescence was utilized to obtain a selective sensing platform for H₂O₂ with various limits of detection. Cotton was impregnated with copper nanoparticles and used to remove H₂O₂ in a prototype application and its efficacy was quantified via copper-enhanced fluorescence.
