Photo-Nanozyme-Integrated Photoelectrochemical-Electrochemical Dual-Mode Biosensor: Enabling Amplification-Free Detection of miRNA-133a in Acute Myocardial Infarction

Analytical Chemistry, Год журнала: 2025, Номер unknown

Опубликована: Март 20, 2025

Acute myocardial infarction (AMI) is a leading cause of death and disability worldwide. MicroRNA-133a (miRNA-133a) serves as valuable biomarker for AMI, offering specificity stability an early diagnosis. However, existing miRNA biosensors faced challenges in detecting low concentrations, ensuring accuracy, maintaining immunity to interference. This study presents novel 1D/2D bismuth vanadium oxide (BiVO4) copper-tetraphenylporphyrin (Cu-TCPP) metal-organic framework heterojunction, constructed via simple electrodeposition method, which enabled the development amplification-free photoelectrochemical/electrochemical (PEC-EC) dual-mode sensor. The S-type heterojunction formed between Cu-TCPP BiVO4 significantly improved separation efficiency photogenerated carriers. Furthermore, peroxidase-like catalytic activity facilitated signal amplification through photonanozyme mechanism. Experimental results demonstrated that sensor achieved high sensitivity with extremely detection limits 0.003 fM PEC 0.02 EC, along excellent selectivity, stability, reproducibility. provides efficient platform miRNA-133a, highlighting its potential diagnosis monitoring diseases linked biomarkers.

Chemosensors, Год журнала: 2025, Номер 13(4), С. 146 - 146

Опубликована: Апрель 16, 2025

The development of cost-effective, rapid-response, and user-friendly biosensing platforms has become paramount importance for achieving precise biomarker quantification in early disease detection. Implementing timely diagnostic interventions through accurate analysis not only significantly improves treatment outcomes but also enables effective management strategies, ultimately leading to substantial reductions patient mortality rates. These clinical imperatives have consequently driven the innovation portable point-of-care (POC) systems. Electrochemical biosensors are attractive diagnosis diseases due their low cost, simple operation, high sensitivity. This review examines prevalent material innovations electrode functionalization electrochemical platforms, with specific emphasis on translational applications early-stage included three important types: proteins, nucleic acids, small molecule metabolites. Furthermore, work proposes novel research trajectories next-generation biosensor development, advocating synergistic integration artificial intelligence-driven analytics, Internet Medical Things (IoMT)-enabled networks, advanced micro/nanofabrication techniques.
