Published: May 14, 2024

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. This review new insight synergistic effects integrating other techniques, aiming shed light on near‐future developments EC‐integrated biosensors.

Nonspecific adsorption (NSA) impacts the performance of biosensors in complex samples. Coupled electrochemical–surface plasmon resonance (EC-SPR) offer interesting opportunities to evaluate NSA. This review details main solutions minimize fouling electrochemical (EC), surface (SPR) and EC-SPR biosensors. The discussion was centered on blood, serum milk as examples matrices. Emphasis placed antifouling coatings, NSA evaluation protocols universal functionalization strategies obtain In last 5 years, various coatings were developed for EC biosensors, including new peptides, cross-linked protein films hybrid materials. Due comparatively much more scarce literature, SPR extended early 2010s. analysis revealed a wide range materials with tunable conductivity, thickness functional groups that can be tested future EC-SPR. high-throughput screening materials, molecular simulations machine learning-assisted evaluations will even further widen available minimization NSA’s impact analytical signal is moreover facilitated by unique sensing mechanisms associated bioreceptor or particularities detection method.
