Quenching Process

In this study, fluorescence spectrum and UV-vis absorption spectrum were employed to explore the interactions between magnetic iron oxide nanoparticles modified by citric acid (CA-MION) and CdTe quantum dots modified by thioglycolic acid (TGA-CdTe QDs). Significantly, the mechanism was demonstrated as a dynamic quenching process based on energy transfer. Taken together, these results showed the decreased fluorescence intensity of CdTe QDs implied satisfactory linear relationship with various concentrations of CA-MION ranged from 0.15×10-3 mol·L-1 to 4.5×10-3 mol·L-1. Overall, this study has provided the potential for preparing multimagnetic-fluorescent nanocomposites and further developing quantitative detections of multi-analytes.
