1. A system for detecting an analyte in a fluid comprising:

  • a light source;

    a sensor array, the sensor array comprising a supporting member comprising at least one cavity formed within the supporting member;

    at least one particle, wherein the particle is positioned within at least one cavity, and wherein the particle comprises an indicator coupled to a polymeric resin, and wherein the indicator is disposed in a core region of the polymeric resin, and wherein the indicator is substantially absent from an exterior region of the polymeric resin; and

    a detector, the detector being configured to detect the interaction of the analyte with at least one particle during use;

    wherein the light source and detector are positioned such that light passes from the light source, to the particle, and onto the detector during use.
