摘要:
The present invention relates to a chemical compound or a salt or solvate thereof being a phenazine-, phenanthridine-, phenanthroline-, quinoline-, quinoxaline-, acridine-isoquinoline-, pyrazine- or pyridine-derivative comprising a conjugated π-system and a π-acceptor group, and to uses thereof. The present invention further relates to a chemistry matrix and to a test element comprising the chemical compound of the present invention. The present invention also relates to a method of determining the amount of an analyte in a test sample, comprising contacting said test sample with a chemical compound, with a chemistry matrix, or with a test element of the invention and estimating the amount of redox equivalents liberated or consumed by the chemical compound, by the chemical compound comprised in said chemistry matrix, or by the chemical compound comprised in said test element, in the presence of said test sample, thereby determining the amount of an analyte in said test sample. Moreover, the present invention relates to a system comprising a test element according to the present invention and a device comprising a sensor for measuring the amount of redox equivalents liberated or consumed.
摘要:
The invention relates to a method for determining the concentration of an analyte in a fluid sample by means of a reagent system, wherein the reaction of the sample with the reagent system results in a change of the amount of a fluorophore, the amount of the fluorophore correlates to the concentration of the analyte, a measurement variable characteristic of the amount of the fluorophore is measured, and the concentration of the analyte is calculated by means of an evaluation algorithm based on the measurement variable. The method is characterized in that the reagent system is integrated into an analysis element, and the fluorescence life span of the fluorophore is utilized in the calculation of the concentration of the analyte.
