{"product_id":"cfebqspce","title":"Quadruple Screen-Printed Carbon Electrode (4WE-SPCE) as Flexible Electrochemical Biosensors, CFEBQSPCE","description":"\u003cp\u003eA Quadruple Screen-Printed Carbon Electrode (4WE-SPCE) integrates four independently addressable carbon working electrodes (WE1–WE4) with a shared counter electrode (CE) and reference electrode (RE) on a single planar strip (typically alumina ceramic or PET). This 6-lead configuration enables four-target multiplexing, in-situ multi-point calibration, or high-confidence replicate testing within a single micro-droplet (50–100 uL).\u003c\/p\u003e\n\u003cp\u003eThe Main Operating Modalities: (1) \u003cstrong\u003eQuadruplex Multiplexed Panels\u003c\/strong\u003e: Functionalizing each carbon disk with a unique biological capture receptor or nanomaterial catalyst. \u003cem\u003eMultiplexed Biomarker Panels\u003c\/em\u003e: Simultaneous detection of cardiac panels (cTnI, NT-proBNP, D-Dimer, and Myoglobin) or multi-pathogen panels (e.g., SARS-CoV-2, Flu A, Flu B, RSV) in clinical point-of-care diagnostics. \u003cem\u003eEnvironmental Heavy-Metal Screening\u003c\/em\u003e: Concurrent or selective stripping detection of Zn^{2+}, Cd^{2+}, Pb^{2+}, Cu^{2+}. (2) \u003cstrong\u003eDual-Target with Dual-Reference Architecture\u003c\/strong\u003e: \u003cem\u003eWE1 \u0026amp; WE2 (Target Channels)\u003c\/em\u003e: Specific biosensing receptors for two distinct disease markers. \u003cem\u003eWE3 (Negative Control)\u003c\/em\u003e: Blocked with non-specific proteins (e.g., BSA or scrambled oligonucleotides) to quantify and subtract complex matrix fouling in whole blood, saliva, or raw wastewater. \u003cem\u003eWE4 (Internal Calibrant)\u003c\/em\u003e: Surface-tethered with an invariant redox active tag (e.g., ferrocene or methylene blue) to normalize for temperature fluctuations, active area variations, or bulk viscosity shifts. (3) \u003cstrong\u003eOn-Chip Statistical Replicates (n=4)\u003c\/strong\u003e: Coating all four electrodes with identical sensing films. A single run produces four independent Faradaic measurements, automatically yielding an on-chip relative standard deviation (RSD) to flag outlier readings.\u003c\/p\u003e\n\u003ctable border=\"1\" style=\"width: 100.071%; height: 241.4px;\"\u003e\n\u003ctbody\u003e\n\u003ctr style=\"height: 47.6px;\"\u003e\n\u003ctd style=\"width: 24.8016%; height: 47.6px;\"\u003ePart Number\u003c\/td\u003e\n\u003ctd style=\"width: 74.9846%; height: 47.6px;\"\u003e\n\u003cul\u003e\n\u003cli\u003eCFEBQSPCE (C-FEB-QSPCE)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 146.2px;\"\u003e\n\u003ctd style=\"width: 24.8016%; height: 146.2px;\"\u003eCritical Features\u003c\/td\u003e\n\u003ctd style=\"width: 74.9846%; height: 146.2px;\"\u003e\n\u003cul\u003e\n\u003cli\u003eSubstrate Material: PET (thickness=0.28 mm)\u003c\/li\u003e\n\u003cli\u003eWorking Electrode (WE1\/WE2\/WE3\/WE4): Carbon Film (Φ 3mm)\u003c\/li\u003e\n\u003cli\u003eCounter Electrode (CE): Carbon\u003c\/li\u003e\n\u003cli\u003eReference Electrode (RE): Ag\/AgCl\u003c\/li\u003e\n\u003cli\u003eAn adapter is included for operation. \u003c\/li\u003e\n\u003cli\u003eStorage Conditions: RT, avoid light illumination, Al bags sealing, ~50%RH \u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 47.6px;\"\u003e\n\u003ctd style=\"width: 24.8016%; height: 47.6px;\"\u003ePackage Grade\u003c\/td\u003e\n\u003ctd style=\"width: 74.9846%; height: 47.6px;\"\u003e\n\u003cul\u003e\n\u003cli\u003e25 pcs\/pack\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003cp\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eReferences\u003c\/strong\u003e:\u003c\/p\u003e\n\u003col\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/pubs.rsc.org\/ay\/article-abstract\/12\/12\/1547\/632819\/Applications-of-electrochemical-sensors-and\"\u003eH.
