The invention discloses a thermosensitized thyroglobulin electrochemiluminescence sensor based on MXenes-ZnO QDs, which is characterized by introducing ZnO QDs with high quantum yield and good biocompatibility into Ru(bpy) 3 2+ /S 2 O 8 2- system, which acts as a co-reaction accelerator greatly improves the luminous efficiency of Ru(bpy) 3 2+ /S 2 O 8 2- system. In addition, MXenes as probe substrates increased the loadings of the luminescent reagent Ru(bpy) 3 2+ and the co-reaction accelerator ZnO QDs to enhance the ECL signal. Moreover, MXenes have excellent photothermal conversion efficiency, can form a temperature gradient layer on the electrode surface, accelerate the diffusion rate of electroactive substances to the electrode surface, further enhance the ECL signal and improve the detection sensitivity. The invention can be used for the detection of thyroglobulin (Tg) and obtain better detection results. |
