| 1. A method of forming a biosensor, the method comprising the steps of:
providing a flexible substrate coated with an electrically conductive material,
ablating through the electrically conductive material to expose the substrate in a pre-defined pattern so as to form a pattern
of electrodes and a code pattern electrically isolated from the electrodes, wherein there is sufficient contrast between the
conductive material and the exposed substrate such that the code pattern is discernible, and
applying a reagent to at least one of the electrodes.
