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.

Laccase-based biosensors are efficient for detecting phenolic compounds. However, the instability and high cost of laccases have hindered their practical utilization.In this study, we developed hierarchical manganese dioxide-copper phosphate hybrid nanoflowers (H-Mn-Cu NFs) as excellent laccase-mimicking nanozymes. To synthesize H-Mn-Cu NFs, dioxide (MnO2 were first synthesized by rapidly reducing potassium permanganate using citric acid. The MnO2 NFs then functionalized with amine groups, followed incubation copper sulfate three days at room temperature to drive coordination interaction between moieties ions induce anisotropic growth petals composed crystals, consequently yielding NFs. Compared those free laccase, same mass concentration, exhibited lower Km (~ 85%) considerably higher Vmax 400%), well significantly enhanced stability in ranges pH, temperature, ionic strength, periods evaluated. also catalyzed decolorization diverse dyes faster than laccase. Based on these advantageous features, a paper microfluidic device incorporating was constructed convenient visual detection neurotransmitters, including dopamine epinephrine. enabled rapid sensitive quantification target neurotransmitters an image acquired smartphone.These results clearly show that could be potential candidates replace natural wide range applications biosensing, environmental protection, biotechnology.

Recently, the utilization of metal halide perovskites in sensing and their application environmental studies have reached a new height. Among different perovskites, cesium lead (CsPbX3; X = Cl, Br, I) composites attracted great interest applications owing to exceptional optoelectronic properties. Most CsPbX3 nanostructures possess structural stability, luminescence, electrical properties for developing distinct optical photonic devices. When exposed light, heat, water, can display stable utilities. Many been reported as probes detection diverse analytes, such ions, anions, important chemical species, humidity, temperature, radiation photodetection, so forth. So far, covering all metallic organic–inorganic already reviewed many studies. Nevertheless, detailed review utilities could be helpful researchers who are looking innovative designs using these nanomaterials. Herein, we deliver thorough composites, quantitation chemicals, explosives, bioanalytes, pesticides, fungicides, cellular imaging, volatile organic compounds (VOCs), toxic gases, radiation, photodetection. Furthermore, this also covers synthetic pathways, design requirements, advantages, limitations, future directions material.

Analytical methods for the early detection of neurodegenerative biomarker Parkinson’s disease (PD), α-synuclein, are time-consuming and invasive, require skilled personnel sophisticated expensive equipment. Thus, a pain-free, prompt simple α-synuclein biosensor in plasma is highly demanded. In this paper, an electrochemical based on hierarchical polyglutamic acid/ZnO nanowires decorated by gold nanoparticles, assembled as nanostars (NSs), determination human proposed. ZnO NSs were prepared chemical bath deposition (CBD) with electrodeposited Au nanoparticles (Au NPs). Then, electro-polymerized glutamic acid was grown functionalized anti-α-synuclein. A synergistic enhancement electrode sensitivity observed when NPs embedded into NSs. The analytical performance evaluated cyclic voltammetry (CV) impedance spectroscopy (EIS), using Fe(II)(CN)64−/Fe(III)(CN)63− probe. charge transfer resistance after recognition found to be linear, concentration range 0.5 pg·mL−1 10 pg·mL−1, limit 0.08 good reproducibility (5% variation) stability (90%). also shown reliably discriminate between healthy PD plasma. These results suggest that proposed provides rapid, quantitative high-sensitivity result content plasma, represents feasible tool capable accelerating non-invasive identification disease.
