Abstract Nanozymes with atomically dispersed metal sites (ADzymes), especially single‐atom nanozymes, have attracted widespread attention in recent years due to their unique advantages mimicking the active of natural enzymes. These nanozymes not only maximize exposure catalytic but also possess superior activity performance, achieving challenging reactions. position ADzymes as highly promising candidates field sensing and biosensing. This review summarizes classification properties ADzymes, systematically highlighting some typical regulation strategies involving central metal, coordination environment, etc., achieve catalytical activity, specificity, multifunctionality. Then, we present advances different fields, including colorimetry, fluorescence, electrochemistry, chemiluminescence, photoelectrochemistry, electrochemiluminescence. Taking advantage resultant show great potential goal sensitivity, selectivity accuracy for detection various targets. Specifically, underlying mechanisms terms signal amplification were discussed detail. Finally, current challenges perspectives on development advanced are discussed.

Abstract Magnesium, a highly reactive alkaline earth metal, acts spontaneously as strong reducing agent. In this work, the redox reactivity of Mg is fine‐tuned selectively in wireless manner by means bipolar electrochemistry (BE). This demonstrated mapping spatial electroactivity via electrochemiluminescence (ECL) emission Ru(bpy) 3 2+ /S 2 O 8 2− system. Asymmetric ECL patterns are obtained controlling applied external electric field. The intensity increased up to approximately 80 % at cathodic extremity whereas 50 decrease observed anodic side electrode. Additionally, influence distribution field on and its concomitant evaluated, producing complex luminescent patterns. These findings, illustrate modulation BE.

The dual-signal output self-calibration mode reduces the false positive and negative signals of electrochemiluminescence (ECL) aptamer sensors. A competitive ECL platform was designed for ultrasensitive detection kanamycin (KAN) using a zirconium metal–organic framework (Zr MOF) Luminol as emitters. To enhance efficiency, co-reactant (polyethyleneimine, PEI) covalently bound to Zr MOF achieve self-enhanced ECL. Based on selective interaction between KAN its aptamer, Luminol/KAN/Zr MOF-PEI “sandwich” structure immobilized electrode surface. competition PEI emitters increased signal decreased MOF’s signal. ratio in two enabled quantitative analysis KAN, achieving limit low 7.86 × 10−4 ng/mL. This study elucidated synergistic mechanism competition, offering novel approach constructing sensors single co-reactant.
