Analyte sensors featuring working electrode asperity planing for decreasing interferent signal

A method of creating a laser planed working electrode comprising:

• laser singulating a working electrode from a template carbon substrate material into a shape, the working electrode comprising an active area disposed thereon, the active area having an analyte-responsive enzyme,
• wherein the laser singulated working electrode comprises electrode asperities at an outermost edge thereof;
• and
• laser planing at least a portion of the outermost edge to remove at least a portion of the electrode asperities at the outermost edge,
• wherein the laser planing comprises making a plurality of spaced apart cuts between a midline length and the outermost edge of the laser singulated working electrode to create an outer beveled edge of the shape, thereby resulting in the laser planed working electrode, wherein a depth of each of the plurality of spaced apart cuts is less than a thickness of the working electrode.
