Biosensor and its use to indicate the status of a product

Abstract

A biosensor comprises a unit, comprising a substrate and an enzyme, which when brought into contact with the substrate is adapted to affect the substrate so that its conductivity changes as a function of time and temperature, and an electric circuit. The unit is included as a component in said electric circuit and the electric circuit is activable by applying an electric field and/or a magnetic field over the same to generate a measurable signal which is dependent on the total resistance of the circuit. The invention also relates to the use of a biosensor, a label with such a biosensor and a method of indicating the status of a product with such a biosensor.

    by applying an electric field and / or a magnetic field over the same to generate a measurable signal which is dependent on the total resistance of the circuit. The invention also relates to the use of such a biosensor, a label with such a biosensor, and a method for indicating the status of a product with such a biosensor. ved påtrykking av et elektrisk felt og/eller et magnetisk felt over den samme for å generere et målbart signal som er avhengig av kretsens totale resistans. Oppfinnelsen vedrører også anvendelsen av en slik biosensor, en merkelapp med en slik biosensor samt en fremgangsmåte til å indikere statusen til et produkt med en slik biosensor.
