1. A method of manufacturing a plurality of electrochemical sensors, the method comprising the steps of:

  • forming a plurality of individual working electrodes on a first substrate;

    forming a plurality of individual counter electrodes on a second substrate;

    positioning a spacer layer on the first substrate;

    following positioning of the spacer layer, removing a plurality of portions of the spacer layer to define sample chamber regions across the plurality of individual working electrodes on the first substrate;

    depositing a reagent layer in the sample chamber regions across the plurality of individual working electrodes on the first substrate;

    overlaying the first substrate with the second substrate to form a layered structure by positioning the second substrate on the spacer layer; and

    separating the layered structure into a plurality of electrochemical sensors, each electrochemical sensor comprising at least one working electrode, at least one counter electrode, and at least one sample chamber region.
