  • Patent number: 8008037
    Abstract: A chemistry matrix for use in determining the concentration of an analyte in a biological fluid includes a glucose dehydrogenase, nicotinamide adenine dinucleotide, an alkylphenazine quaternary salt, and/or a nitrosoaniline. The chemistry matrix is used with an electrochemical biosensor to determine the concentration of an analyte after a reaction occurs within the biosensor, at which time an analysis is completed to determine the concentration. A method of determining the concentration of an analyte using the chemistry matrix of glucose dehydrogenase, nicotinamide adenine dinucleotide, an alkylphenazine quaternary salt, and/or a nitrosoaniline is another aspect that is described. The method also further features test times of five seconds or less. Methods utilizing the new chemistry matrix can readily determine an analyte such as blood glucose at concentrations of from about 20-600 mg/dL at a pH of from about 6.5 to about 8.5.

  • Patent number: 7855287
    Abstract: A process is described for preparing, efficiently and with a high degree of purity N-alkylsulfonates of phenothiazine. The process consists in (a) the preparation of the phenothiazine anion, and (b) the reaction of said anion with cyclic alkyl sulfonates, such as 1,3-propane sultone and 1,4-butane sultone. This process is simpler, more direct, and more efficient than the procedures currently used for the synthesis of N-alkylsulfonates derivatives of phenothiazine. In addition, the products obtained with this process are far more pure than those obtained through current procedures and therefore ideal for bioanalytical applications that require high sensitivity, such as assays based on the measurement of peroxidase activity using chemiluminescence.
