The present invention concerns an electrochemical sensor made up of an insulating base having an electrode layer on its surface and a lid of deformable material which comprises a concave area in the central portion thereof, so that when it is mated with the base, the lid and base form a capillary space containing the electrode layer. When the electrode layer is in operative contact with a reaction layer comprising an enzyme which will cause the production of mobile electrons when contacted with a suitable analyte, the concentration of analyte, e.g. glucose in blood, can be measured by measuring the current created by the flow of mobile electrons when contacted with a suitable analyte, the concentration of analyte, e.g. glucose in blood, can be measured by measuring the current created by the flow of mobile electrons.
An electrochemical sensor for the detection of an analyte in a fluid test sample which comprises from the bottom up:
A method for the preparation of an electrochemical sensor which comprises mating a base which carries an electrode structure on its surface with a lid of a deformable material which provides a concave space to form three sides of a capillary space which lid and base provide an electrochemical sensor having a capillary space which is open to the atmosphere with an electrode structure on the surface of the base and exposed to the capillary space.
A method for the production of a multiplicity of electrochemical sensors which comprises:
