BIOSENSOR SYSTEM AND METHOD FOR MEASURING CONCENTRATION OF ANALYTE

摘要

A biosensor system can be provided with a sensor chip and a measuring unit. The sensor chip is provided with a capillary and an electrode disposed within the capillary. The height of the capillary is set at a value smaller than the maximum value of the total of the diffusion distance of the analyte at the upper limit temperature of the measurement guaranteed temperature of the biosensor system and the diffusion distance of an electronic mediator. Before the concentration measurement, the measuring unit applies, for example, a voltage lower than the open circuit voltage or the voltage applied when the concentration is measured to the electrode of the sensor chip.
