Analyte sensors featuring enhancements for decreasing interferent signal

A method comprising:

• providing a sensor control device including a sensor housing, circuitry disposed within the sensor housing, and an analyte sensor having a proximal portion and a distal portion, wherein the proximal portion is electrically coupled with the circuitry, wherein the distal portion extends from an underside of the sensor housing and is configured to extend beneath a user's skin to measure an analyte level in a bodily fluid, the distal portion
• comprising:
• a laser planed working electrode comprising an active area disposed thereon, the active area including an analyte-responsive enzyme, and
• a scrubbing electrode, wherein the scrubbing electrode is positioned above the laser planed working electrode and is permeable to an analyte of interest for diffusion of the analyte of interest to the active area;
• and
• exposing the analyte sensor to a bodily fluid.

An analyte monitoring system comprising:

• a sensor control device including a sensor housing;
• circuitry disposed within the sensor housing;
• and
• an analyte sensor having a proximal portion and a distal portion, wherein the proximal portion is electrically coupled with the circuitry, wherein the distal portion extends from an underside of the sensor housing and is configured to extend beneath a user's skin to measure an analyte level in a bodily fluid, the distal portion including:
• a laser planed working electrode comprising an active area disposed thereon, the active area including an analyte-responsive enzyme, and
• a scrubbing electrode, wherein the scrubbing electrode is positioned in a facing relationship to the active area of the working electrode, wherein the working electrode and the scrubbing electrode are separated by a layer between the working electrode and the scrubbing electrode and configured to permit bodily fluids to pass between the working electrode and scrubbing electrode, and wherein the scrubbing electrode is permeable to an analyte of interest for diffusion of the analyte of interest to the active area.
