In biosensor system 1, biosensor 2 is mounted in measuring apparatus 3 for quantifying or detecting existence of a targeted substrate in a sample solution. Mounting end portion 20 of biosensor 2 to be mounted in measuring apparatus 3 has an extension of one base plate in the length direction, and further extensions of the other base plate in the width direction. Sensor mounting portion 30 of measuring apparatus 3 has a shape matching up with the shape of mounting end portion 20. Thereby wrong insertion of biosensor 2 in measuring apparatus 3 can be prevented.Further, varying shapes of plural biosensors 5 and 6 to have a common part and a non-common part, such biosensors can be handily measured by one measuring apparatus 7.
摘要:
A biosensor capable of measuring the concentration of one or more specific substances in one or more sample solutions almost simultaneously is provided. The biosensor comprises a plurality of sensor units, and each of the sensor units comprises an electrode system including a working electrode and a counter electrode on an insulating base plate and a reagent system including an oxidoreductase and an electron mediator. The biosensor is so configured that sample solutions supplied to the respective sensor units reach the respective reagent systems at different times. Specifically, each of the sensor units has a controlling system between a sample supply inlet and the reagent system, and the controlling system controls the time it takes for the sample solution to reach the reagent system from the sample supply inlet.
