Abstract | Cited by

We report for the first time the enzymatic etching of cadmium sulfide nanoparticles (CdS NPs). The fluorescence of semiconductor CdS NPs is modulated irreversibly by an enzymatic reaction catalyzed by horseradish peroxidase (HRP). We observed blue-shifts of the corresponding fluorescence peaks for CdS NPs and a decrease in the intensity of the fluorescence signal.
