The length, width, and height of the metallic antenna determines an infrared absorption of the pair of metallic antennas. The device also includes a gap located between the pair of metallic antennas. A chemical moiety is disposed on at least a portion of the metallic antennas such that the infrared absorption of the chemical moiety is enhanced by the at least one pair of metallic antennas.18engUtility patentUS9372151B2
