The fluorescence spectra changes with applied potential.
(a–c), The fluorescence emission spectra of Q2NS (a), Q5NS (b) and Q10NS (c) functionalised CdSe/ZnS QDs changes with applied potential. At the applied potential of −0.30 V vs. SCE, the fluorescence intensity of QD bioconjugates gradually increased. At a constant applied potential of 0.10 V vs. SCE, the fluorescence intensity decreased over time. (d–f), Time-dependent fluorescence intensity changes upon the redox cycle of Q2NS (d), Q5NS (e) and Q10NS (f) functionalised CdSe/ZnS QDs with applied potential. The fluorescence cyclic change follows with a cyclic change of the electrolysis time.
