Energy-Transfer-Based Dual-Mode PEC-ECL Biosensor for Acetamiprid Analysis Sensitized by Two-Step DNA Circuit Amplification

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) and electrochemiluminescent (ECL) donors and Pt@Cu
