Method of making a biosensor
View Patent ↗The present invention relates to a method of forming a biosensor. The method includes providing a substrate coated with a electrically conductive material, ablating the electrically conductive material to form electrodes and a code pattern, wherein there is sufficient contrast between the conductive coating and the substrate such that the code pattern is discernible, and applying a reagent to at least one of the electrodes.
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.
2. The method of claim 1 wherein the ablating step includes the step of laser ablating the electrically conductive material.
3. The method of claim 1 wherein the ablating step includes forming a bar code shaped code pattern.
4. The method of claim 1 wherein the ablating step includes forming a code pattern that includes pads isolated from the surrounding electrically conductive material.
