Role of CDs in chemical and bio-sensing via fluorescence quenching: the change in fluorescence intensity of CDs take place via different mechanisms, such as a Conduction band electrons of CDs shifts to low-lying vacant d-orbital of metal ions, b Electron transfer from CB of CDs to CB of metal ions, c Fluorescence resonance energy transfer (FRET), d Inner filter effect
