Abstract: An improved disposable glucose test strip for use in a test meter of the type which receives a disposable test strip and a sample of blood from a patient and performs an electrochemical analysis is made using a non-conductive integrated reagent/blood separation layer containing a filler, an enzyme effective to oxidize glucose, e.g., glucose oxidase, and a mediator effective to transfer electrons from the enzyme. The integrated layer formulation is printed over a conductive carbon element to form a working electrode. The filler, for example a silica filler, is selected to have a balance of hydrophobicity and hydrophilicty such that one drying it forms a two-dimensional network on the surface of the conductive element. The response of this test strip is essentially temperature independent over relevant temperature ranges and is substantially insensitive to the hematocrit of the patient.

Abstract: A method for manufacturing a portion of an electrochemical-based test strip comprising includes forming a metal electrode(s) with an upper surface on a surface of an electrically-insulating substrate. The method also includes treating the upper surface of the metal electrode(s) with a hydrophilicity-enhancing composition to form a treated upper surface on the metal electrode with hydrophilicity-enhancing chemical moieties thereon and depositing an enzymatic reagent layer on the treated upper surface of the metal electrode(s).

Abstract: An electrochemical-based analytical test strip includes an electrically-insulating substrate and a metal electrode (e.g., a gold metal electrode) disposed on a surface of the electrically-insulating substrate. The metal electrode has an upper surface with hydrophilicity-enhancing chemical moieties thereon. In addition, the electrochemical-based analytical test strip also includes an enzymatic reagent layer disposed on the upper surface of the metal electrode.

Abstract: A device and method for measuring clotting times in a fluid, typically blood, within a microchannel, with the onset of clotting being determined by measurement of the rate of change, or the value, of capacitance or impedance between two electrodes situated on either side of the microchannel. The device includes an upper support member and a lower support member with a microchannel formed therein. The device also includes electrodes situated along the length of the microchannel.

Abstract: A device and method for measuring the clotting times in a fluid, typically blood, within a microchannel whereby the onset of clotting is determined by measurement of the rate of change or value of capacitance or impedance between two electrodes situated on either side of the microchannel. There is provided a disposable test-strip (100) comprising an upper and lower support (101) and (103). A microchannel (102) is formed into the upper surface of the lower support member (103). A second substrate layer (101) is laminated on top of the support member (103), thereby closing the open microchannel (102). Electrodes (104) are formed on the respective outer surfaces of the substrate layers and coplanar to the channel.
