1. A method of using a sensor device for measuring a concentration of a substance within a sample comprising the steps of:

  • inserting a tip portion of a sensor into a sample, the sensor comprising an optical transmission member having a first end and a second end, the second end having the tip portion attached thereto and an active material incorporated within the tip portion, the active material capable of interacting with a substance within the sample;

    emitting a beam of light into the first end of the sensor, through the optical transmission member and the tip portion and into the sample, the beam of light having a first wavelength;

    producing a reflected beam of light from the interaction of the active material with the substance within the sample, the reflected beam of light having a second wavelength different from the first wavelength;

    receiving the reflected beam of light and producing a signal indicative of the reflected beam of light; and

    determining the concentration of the substance within the sample based on the produced signal.
