  • Publication number: 20040050694
    Abstract: A portable multi-functional electrochemical biosensor system includes a plurality of sample cells, pluggable information memories and a multi-functional signal analysis processor. The biosensor system uses a set of sample cell and pluggable information memory to detect the concentration of a corresponding selected analyte. Each sample cell has a reaction zone on which a chemical substance is placed to react with the corresponding analyte and has at least two independent electrodes. During detection, each corresponding pluggable information memory can provide parameters used for analysis. The multi-functional signal analysis processor has a microprocessor, an electrically erasable programmable read/write memory and an environmental temperature sensor. The concentration of the selected analyte is calculated by using the electrochemical reaction signal output from the sample cell and the parameters with cooperation of the environmental temperature sensor, and then an analysis result is output.

  • Publication number: 20030082076
    Abstract: The subject invention relates to a disposable hemoglobin and hematocrit detecting electrode strip, the preparation and the use thereof. The concentration of hemoglobin and hematocrit in a liquid sample can be determined by electrochemically analyzing the liquid sample under a low operation voltage of below 400 mV. When the electrode strip is applied to detect the concentration of hemoglobin and hematocrit in human body, the whole blood is directly used as the sample. The hemoglobin and hematocrit detecting electrode strip is modified by a water-soluble redox electron mediator. The electrode strip simplifies the analysis of hemoglobin and hematocrit, is conveniently portable and can be easily manufactured in mass-production.

  • Patent number: 6491803
    Abstract: The present invention relates to a test strip and a biosensor having an increased conductivity and a slurry comprising a fiber, meal particles having a size in nanometer and a bioactive substance. The invention is characterized by incorporating metal particles having size in nanometer into the reaction layer of test strip and biosensor to increase the conductivity between the reaction layer and the electrodes so that the redox reaction can be readily completed and the measurement time can thus be shortened.
