Photoinduced Electrochemiluminescence Immunoassays

Analytical Chemistry, Год журнала: 2024, Номер 96(45), С. 18262 - 18268

Optimization of electrochemiluminescence (ECL) immunoassays is highly beneficial for enhancing clinical diagnostics. A major challenge the improvement operation conditions required bead-based using typical [Ru(bpy)3]2+/tri-n-propylamine (TPrA) system. In this study, we report a heterogeneous immunoassay based on near-infrared photoinduced ECL, which facilitates imaging and quantitative analysis [Ru(bpy)3]2+-modified immunobeads at low anodic potential. The photovoltage generated by photoanode under light promotes oxidation processes electrode/electrolyte interface, thus considerably lowering onset potential both TPrA ECL emission. anti-Stokes shift between excitation (invisible to human eyes) visible emitted results in clear stable signal from immunobeads. addition, it offers possibility site-selective photoexcitation process. This approach not only meets performance traditional accuracy but also additional benefits lower requirements enhanced stability, providing new perspective optimization commercial immunoassays.
