Sensitive and accurate determination of acetamiprid is highly desirable for guaranteeing food safety. In this Letter, an energy-transfer-based dual-mode biosensor was developed using zinc-based metal-organic frameworks (Zn-MOFs) acting as both photoelectrochemical (PEC) electrochemiluminescent (ECL) donors Pt@Cu

Electrochemiluminescence (ECL)/electrochemistry (EC) dual-mode sensors have garnered significant interest for their enhanced analytical reliability through the cross-verification of dual-signal outputs. However, conventional approaches necessitate two potential scans to acquire ECL and EC signals independently, resulting in temporal environmental discrepancies between detection modes. In this paper, we present a novel synchronous ECL/EC sensing platform lead ion (Pb2+) via one-step scan (0.2 -0.4 V vs. Ag/AgCl) utilizing G-quadruplex (G4)-hemin DNAzyme complex. This complex synergistically catalyzed electrochemical reduction dissolved oxygen, concurrently generating distinct cathodic emission from Ru(bpy)32+ current peak at -0.25 V. Pb2+ quantification was achieved its dose-dependent suppression activity by destabilizing G4-hemin interaction, thereby proportionally attenuating both intensity signal (reduction current). The integrated sensor demonstrated high sensitivity (detection limits 1.51 nM 2.03 detection), robust anti-interference capability, satisfactory reproducibility, with recoveries ranging 95.5 103.1% water analysis. work established paradigm design, offering new prospects monitoring.
