Abstract:
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, and wherein the cavity is configured such that the fluid entering the cavity passes through the supporting member; a particle, the particle positioned within the cavity, wherein the particle is configured to produce a signal when the particle interacts with the analyte during use, and wherein the cavity is configured to substantially inhibit movement of the particle within the support member; and a cover positioned at a distance above the upper surface of the supporting member such that an opening is formed between the supporting member and the cover to allow the fluid to enter the cavity via the opening, and wherein the cover inhibits dislodgment of the particle from the cavity during use; a detector, the detector being configured to detect the signal produced by the interaction of the analyte with the 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.
