“…Based on a suitable aptasensor, a wide range of molecules can be efficiently detected, such as kanamycin [108], sulfadimethoxine [109], and isocarbophos [110]. Apart from the aptamer, a competition-type ECL immunosensor using Pt NPs@MOFs for the quantitative detection of trenbolone was successfully constructed, demonstrating the simplicity of framework-based ECL systems [111]. Based on the quenching effect between MOF radicals and oxidized dopamine (Figure 11b), dopamine can be analyzed without the aid of an aptamer [55].…”

Electrochemiluminescence (ECL) has attracted increasing attention owing to its intrinsic advantages of high sensitivity, good stability, and low background. Considering the fact that framework nanocrystals such as metal–organic frameworks and covalent organic frameworks have accurate molecular structures, a series of framework-based ECL platforms are developed for decoding emission fundamentals. The integration of fluorescent ligands into frameworks significantly improves the ECL properties due to the arrangement of molecules and intramolecular electron transfer. Moreover, the various framework topologies can be easily functionalized with the recognition elements to trace the targets for signal readout. These ECL enhancement strategies lead to a series of sensitive analytical methods for protein biomarkers, DNA, small biomolecules, and cells. In this review, we summarize recent advances in various functions of frameworks during the ECL process, and constructions of framework-based ECL platforms for biosensing. The framework-based ECL nanoemitters and enhancement mechanisms show both theoretical innovation and potential applications in designing ECL biosensing systems. Perspectives are also discussed, which may give a guideline for researchers in the fields of ECL biosensing and reticular materials.

“…Metal-organic framework (MOF) is a composite material self-assembled by organic ligands and metal ions through coordination bonds, with an internal microporous structure. It can take advantage of the electrochemiluminescence activity of the organic ligand itself, and can also be combined with the electrochemiluminescence active substance to enhance its luminescence performance [94]. Liu and his group synthesized Ag-MOF as an electrochemiluminescence luminophore for the detection of mercury ions in water samples [95].…”

Metal ion contamination has serious impacts on environmental and biological health, so it is crucial to effectively monitor the levels of these metal ions. With the continuous progression of optoelectronic nanotechnology and biometrics, the emerging electrochemiluminescence (ECL) biosensing technology has not only proven its simplicity, but also showcased its utility and remarkable sensitivity in engineered monitoring of residual heavy metal contaminants. This comprehensive review begins by introducing the composition, advantages, and detection principles of ECL biosensors, and delving into the engineered aspects. Furthermore, it explores two signal amplification methods: biometric element-based strategies (e.g., HCR, RCA, EDC, and CRISPR/Cas) and nanomaterial (NM)-based amplification, including quantum dots, metal nanoclusters, carbon-based nanomaterials, and porous nanomaterials. Ultimately, this review envisions future research trends and engineered technological enhancements of ECL biosensors to meet the surging demand for metal ion monitoring.
