1. A sensor system comprising:

  • a sensor having a chemically reactive surface that reacts with an analyte to be sensed; and

    a cannula comprising;

    a substantially cylindrical housing that surrounds the sensor;

    at least one aperture disposed in the housing that allows the analyte to diffuse therethrough so as to contact the chemically reactive surface;

    an end that extends beyond an end of the sensor;

    an accessory material provided in proximity to the chemically reactive surface, wherein;

    the accessory material fills the at least one aperture of the cannula;

    the accessory material is disposed in the aperture such that a surface of the accessory material is substantially flush with a surface of the cannula; and

    the sensor system is adapted to contact a tissue such that the accessory material is configured to contact and modify a biological response of the tissue.
