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.
用于确定生物流体中分析物浓度的化学矩阵包括葡萄糖脱氢酶、烟酰胺腺嘌呤二核苷酸、烷基苯并咪唑季铵盐和/或亚硝基苯胺。化学矩阵与电化学生物传感器一起使用,以确定反应在生物传感器内后的分析物浓度,此时进行分析以确定浓度。还描述了使用葡萄糖脱氢酶、烟酰胺腺嘌呤二核苷酸、烷基苯并咪唑季铵盐和/或亚硝基苯胺的化学矩阵来确定分析物浓度的方法。该方法还具有5秒或更短的测试时间。利用新的化学矩阵的方法可以轻松地确定分析物,如血糖,浓度为约20-600 mg/dL,在pH值约为6.5至约8.5。
