{"product_id":"cfebdspce","title":"Dual Screen-Printed Carbon Electrode (2WE-SPCE) as Flexible Electrochemical Biosensors, CFEBDSPCE","description":"\u003cp\u003eA Dual Screen-Printed Carbon Electrode (Dual-SPCE) integrates two independently addressable carbon working electrodes (WE1, WE2) alongside a shared counter electrode (CE) and reference electrode (RE) on a single planar ceramic or polymer (PET) strip. This 4-electrode architecture allows multi-analyte quantification, in-situ background subtraction, or electrochemical signal amplification within a single micro-droplet sample (30–60 uL).\u003c\/p\u003e\n\u003cp\u003eThe standard footprint aligns the electrodes within a shared dielectric reaction well: (1) \u003cstrong\u003eWorking Electrodes (WE1 \u0026amp; WE2)\u003c\/strong\u003e: High-purity graphite\/carbon ink printed as adjacent semicircles, discs, or interdigitated\/parallel microbands separated by an insulating gap (typically 0.5–1.5 mm). (2) \u003cstrong\u003eShared Counter Electrode (CE)\u003c\/strong\u003e: Outer perimeter carbon band sized at 2 times to 4 times the combined area of WE1 + WE2 to avoid limiting the cell's current compliance. (3) \u003cstrong\u003eShared Reference Electrode (RE)\u003c\/strong\u003e: Screen-printed Ag\/AgCl track providing a unified potential baseline for both working channels.\u003c\/p\u003e\n\u003cp\u003eThe Primary Operating Modalities: (1) \u003cstrong\u003eMultiplexed Detection\u003c\/strong\u003e: The dual potentiostat drives WE1 \u0026amp; WE2 at individual target potentials. It can be use for simultaneous quantification of two targets: e.g., WE1 functionalized with Glucose Oxidase and WE2 with Lactate Oxidase, or simultaneous stripping detection of two distinct heavy-metal pairs (Pb^{2+}\/Cd^{2+} vs. Cu^{2+}\/Hg^{2+}). (2) \u003cstrong\u003eDifferential \/ Background Subtraction\u003c\/strong\u003e: WE1 = Target sensing surface; WE2 = Non-functionalized or scrambled-probe control. It can eliminates non-specific interferents: In complex matrices (whole blood, saliva, environmental runoff), subtraction of the baseline signal (Δ I = I_WE1 - I_WE2) cancels out charging currents, matrix fouling, and electroactive interferents (ascorbic acid, uric acid). (3) \u003cstrong\u003eGenerator-Collector Mode\u003c\/strong\u003e: WE1 poised at oxidation potential; WE2 poised at reduction potential. An analyte oxidized at WE1 diffuses to the adjacent WE2, where it is reduced back to its original state and diffuses back to WE1. This continuous regenerative loop magnifies Faradaic current by an order of magnitude.\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\u003eCFEBDSPCE (C-FEB-DSPCE)\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): Carbon (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.
