Abstract Electrochemical (EC) analysis has emerged as a high‐sensitivity, reliable, cost‐effective, and rapidly evolving technique that garnered significant attention across diverse domains. Furthermore, EC‐based techniques hold great potential for miniaturization integration. The integration of EC with mode/signal (such light, magnetic, thermal signals, etc.) provides unique opportunities biosensors to acquire more information through single sensing platform. By coupling multiple signals or processing them logically, the detection accuracy can be further improved, probability false positives negatives minimized. In this review, thorough multi‐ sensors in field is conducted, along their various (e.g., fluorescence, photothermal, colorimetry, microfluidic, etc.). aim delve into latest advances, applications, well challenges multi‐mode/signal biosensors, where utilization modalities helps enhance accuracy, sensitivity, selectivity.

Exosomal microRNAs (exomiRNAs) have emerged as promising biomarkers for the early clinical diagnosis of osteoporosis. However, their limited abundance and short length in peripheral blood present significant challenges accurate detection exomiRNAs. Herein, we designed implemented an efficacious fluorescence-based biosensor highly sensitive exomiRNA associated with osteoporosis, leveraging enhancing 3D DNA walker-induced CRISPR/Cas12a technology. The engineered walker is capable efficiently transforming target into amplifying strands, thereby sensitivity developed biosensor. Concurrently, liberated strands serve activators to trigger Cas12a trans-cleavage activity, culminating a significantly amplified fluorescent signal exomiRNA-214. Under optimal conditions, devised technology demonstrated capacity detect exomiRNA-214 at concentrations low 20.42 fM, encompassing wide linear range extending from 50.0 fM 10.0 nM. Moreover, could accurately differentiate between healthy individuals osteoporosis patients via exomiRNA-214, which was agreement RT-qPCR results.
