HOF-101-based dual-mode biosensor for photoelectrochemical/electrochemiluminescence detection and imaging of oxytetracycline

Recent Advances in Photoelectrochemical Sensing for Food Safety

“…Li et al employed a novel HOF-101, which has outstanding PEC and ECL properties, as the substrate material, and polydopamine was introduced by the dual aptamer interlayer method to quench PEC and electrochemiluminescence (ECL) signals simultaneously (Figure 6D). 76 Finally, the ultrasensitive detection of oxytetracycline was realized by detecting the changes in ECL and PEC dual signals. In addition, the strong ECL signal provided by HOF-101 allows for visual detection.…”

“…To overcome these limitations and enhance the reliability and accuracy of detection, it is necessary to combine PEC sensing technology with other detection techniques, thus establishing multimode sensing platforms. Li et al employed a novel HOF-101, which has outstanding PEC and ECL properties, as the substrate material, and polydopamine was introduced by the dual aptamer interlayer method to quench PEC and electrochemiluminescence (ECL) signals simultaneously (Figure D) . Finally, the ultrasensitive detection of oxytetracycline was realized by detecting the changes in ECL and PEC dual signals.…”

Self-Assembly-Induced Enhancement of Cathodic Electrochemiluminescence of Copper Nanoclusters for a Split-Type Matrix Metalloproteinase 14 Sensing Platform

“…It relies on the redox processes of electrochemical reactions, where electrons or holes are transferred from the electrode to the luminophore in the reaction system at a specific potential, inducing the excited state luminophore to return to its ground state and release photons . As a significant optoelectronic conversion technology, ECL has found extensive applications in various fields such as clinical medicine, , environmental monitoring, , and food analysis , due to its exceptional sensitivity, minimal interference from background signals, and rapid response time . Nevertheless, the exploration of novel luminophores for ECL remains a crucial research focus within this field. − …”

Spatial-Potential-Color-Resolved Bipolar Electrode Electrochemiluminescence Biosensor Using a CuMoOx Electrocatalyst for the Simultaneous Detection and Imaging of Tetracycline and Lincomycin

“…Compared with OBPE, CBPE is more suitable for biochemical analysis due to its spatial separation of cathode and anode solutions, making it free from interferences from nonrelated substances. , Furthermore, CBPE requires a lower applied voltage due to the absence of the current shunt . Electrochemiluminescence (ECL) combines the controllability of electrochemistry with the sensitivity of the chemiluminescence method and has been widely used as a powerful analytical technique in various fields. − In recent years, researchers have combined BPE with ECL technology to build BPE-ECL sensors that have become a research hotspot due to their high throughput, low cost, and high sensitivity. − However, most of the BPE-ECL sensors detect the target under single potential, , and ignore the important influence of positive and negative potential co-regulation on BPE. This work is the first time to use dual potential to regulate the polarity of BPE and then innovatively construct a spatial-potential-color simultaneous resolved BPE-ECL sensor.…”
