    摘要: An electrochemical-based analytical test strip for the determination of an analyte (such as glucose) in a bodily fluid sample (e.g., a whole blood sample) includes an electrically-insulating substrate, at least one working electrode disposed on the electrically-insulating substrate and a graded enzymatic reagent layer disposed on the at least one working electrode. The graded enzymatic reagent layer includes an upper reaction grade that contains an enzyme. The graded enzymatic layer also has a lower spacer grade devoid of the enzyme, the lower spacer grade disposed between the upper reaction grade and the working electrode such that the upper reaction grade is spaced equidistant from the working electrode by the lower spacer grade by a predetermined distance during use of the electrochemical-based analytical test strip. In addition, the upper reaction grade is configured and constituted such that an enzymatic reaction between the enzyme and a bodily fluid sample applied to the electrochemical-based analytical test strip is localized in the upper reaction grade and the lower spacer grade has predetermined mass transport characteristics for a component of the enzymatic reaction that cause mass transport of the component through the lower spacer grade to the working electrode to be slower than mass transport of the analyte through the bodily fluid sample to the upper reaction grade. A method for determining an analyte (such as glucose) in a bodily fluid sample (for example, a whole blood sample) includes applying a bodily fluid sample to such an electrochemical-based analytical test strip.

    摘要: An electrochemical-based sensor includes an electrode with at least one electrode surface, a film disposed on the electrode surface, and a dialysis membrane disposed on the film. The film includes a redox enzyme and a hydrophilic redox polymer (i.e., a polymer with an attached redox mediator(s)). In addition, the dialysis membrane serves to entrap the redox polymer and redox enzyme in the vicinity of the electrode. Such entrapment is accomplished by employing a redox enzyme and a hydrophilic redox polymer of a sufficiently high molecular weight that they do not pass through the dialysis membrane.

    摘要: Ionic hydrophilic high molecular weight redox polymers for use in enzymatic electrochemical-based sensors include a hydrophilic polymer (such as a hydrophilic polymer backbone) with ionic portions (e.g., cationic monomers incorporated in the hydrophilic polymer backbone) and a plurality of attached redox mediators. The redox mediators can be, for example, covalently attached to the hydrophilic polymer in a pendant manner. An exemplary cationic hydrophilic high molecular weight redox polymer is synthesized by co-polymerization of a hydrophilic acrylamide monomer, [2-(acryloyloxy)ethyl]trimethyl ammonium chloride and vinyl ferrocene.

    摘要: A method for manufacturing a portion of an enzymatic electrochemical-based sensor includes applying a water-miscible conductive ink to a substrate of an enzymatic electrochemical-based sensor. The water-miscible conductive ink includes a conductive material, an enzyme, a mediator, and a binding agent (that becomes operatively water-insoluble upon drying) formulated as a water-miscible aqueous-based dispersion. The method further includes the drying the water-miscible conductive ink to form a conductive layer on the substrate that includes an operatively water-insoluble binding agent.
