Abstract A novel cobalt-doped two-dimensional molybdenum diselenide/polypyrrole hybrid-based carbon nanofiber (Co/MoSe 2 /PPy@CNF) was prepared using the hydrothermal method followed by electrospinning technique. The structural and morphological properties of 2D-TMD@CNF-based hybrids were characterized through X-ray photoelectron spectroscopy (XPS), scanning electron microscopy (SEM), energy-dispersive spectrometry (EDS), transmission (TEM). Co-MoSe /PPy@CNF exhibited large surface area, porous structure, improved active sites due to synergistic effect components. electrochemical electrocatalytic characteristics 2D-TMD@CNF-modified electrodes also investigated cyclic voltammetry (CV) differential pulse (DPV) techniques. Co/MoSe electrode used as an sensor for simultaneous detection ascorbic acid (AA), dopamine (DA), uric (UA) showed enhanced catalytic activity sensitivity. Using DPV measurements, demonstrated wide linear ranges 30–3212 μM AA, 1.2–536 DA, 10–1071 UA with low limits 6.32, 0.45, 0.81 μM, respectively. developed /PPy@CNF-modified applied a human urine sample gave recoveries ranging from 94.0 105.5% ( n = 3) UA. Furthermore, /PPy@CNF-based good selectivity reproducibility Graphical abstract

Electrochemical enzyme biosensors are extensively utilized in clinical analysis and environmental monitoring, yet achieving effective immobilization while maintaining high activity remains a challenge. In this work, we developed flow-through biosensor system using 3D-printed electrochemical cell fabricated from commercially available poly (lactic acid). After modification with thiacalixarene-functionalized oligo acids) (OLAs), the material enabled efficient of uricase on inner surface replaceable reactor cell. Swelling hydrolytic stability OLAs cone, partial 1,3-alternate conformations were studied, 1,3-alernate conformation demonstrating superior performance. The use enhanced efficiency by over 30% protected swelling, degradation, loss. was validated for amperometric uric acid determination, screen-printed carbon electrode modified black Prussian Blue. This reduced cathodic potential detection to -0.05 V. exhibited linear range 10 nM 30 μM limit 7 nM, it performed effectively artificial urine synthetic blood plasma. novel design, featuring easy assembly low-cost parts, makes promising candidate routine other practical applications.
