▎ 摘　　要

NOVELTY - Fluid-permeable electrode comprises layer of electroactive material deposited on surface of open cell substrate that is formed of material that differs from the electroactive material or fluid-permeable electrode having open-cell structure and includes electroactive material. USE - Fluid-permeable electrode. ADVANTAGE - The fluid-permeable electrode provides improved the adhesion of the polymer to the substrate. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: a device, which comprises one or more of the fluid-permeable electrodes integrated into fabric, paper, or plastic film substrate;#a fluid-permeable electrochemical cell (ECC), which comprises one or more of the fluid-permeable electrodes and fluid, electrode and fluid are provided inside compartment comprises inlet port and outlet port, and fluid is gas or liquid;#a fluid-permeable analytical device for detection of analyte, biomolecule, metabolite, enzyme, protein, antibody, metal, metallic ions, bacteria, pesticides, or organic pollutant or organic compounds, which comprises fluid-permeable electrochemical flow cell; and#a method for detecting analyte in liquid samples, which involves filling syringe of the device with liquid sample of one or more of environmental water, drinking water, food extracts, liquid beverage, liquid food sample, whole blood, serum, urine and plasma, reagent is either a liquid form or embedded a reagent support substrate, urging liquid sample through the ECC, determining via electrochemical analyzer, concentration of one or more analyte in the liquid sample, one or more analyte includes biomolecule, metabolite, enzyme, protein, antibody, metal, metallic ions, bacteria, pesticides, or organic pollutant or organic compounds and graphing data representing the output of the electrochemical analyzer on the external device to illustrate the concentration; and#a method for detecting analyte in gas, which involves directing gas into the conduit of the device, reagent is either a liquid form or embedded a reagent support substrate, decoupling the conduit from ECC and coupling syringe to the ECC and urging the solution through the ECC, determining via electrochemical analyzer concentration of one or more analyte in the gas, one or more analyte includes organic pollutant or organic compounds, and graphing data representing the output of the electrochemical analyzer on the external device to thereby illustrate the concentration;#a method for disinfecting fluid, which involves urging fluid through ECC of the device, decontaminating the fluid and collecting from the ECC the fluid that is decontaminated;#a method for performing catalytic conversion, which involves placing electrodes in beaker or H-cell, or fluid permeable cell, and engaging electrodes with reagent mixture, and providing power to the electrodes; and#a fluid flow control device, which includes fluid tube wrapped around core so that the tube turns and twists about the core, where fluid tube defines input and output flow rate.
