Potential-Resolved Ratiometric Aptasensor for Sensitive Acetamiprid Analysis Based on Coreactant-free Electrochemiluminescence Luminophores of Gd-MOF and “Light Switch” Molecule of [Ru(bpy)2dppz]2+

“…Electrochemiluminescence (ECL), as an ideal combination of electrochemical and spectroscopic techniques, possesses fascinating merits including near-zero background, high sensitivity, and excellent spatiotemporal controllability. − These appealing superiorities make the ECL technique receive tremendous attention in biosensing, environmental monitoring, and other areas of analytical chemistry. , Nonetheless, the conventional ECL detection system usually involves the single-signal mode, which is vulnerable to other interferences derived from intrinsic or extrinsic factors, resulting in false positive or negative responses. To overcome the inherent defects, various ratiometric ECL sensing strategies with self-rectification functions have been developed, mainly including dual-wavelength and dual-potential detection modes. − Compared with the spectrum-resolved ECL detection, the potential-resolved strategies exclude intricate optical instruments and operations. , Nevertheless, it remains a challenge to design a pair of advanced ECL emitters to achieve dual-potential ratiometric ECL sensing.…”
