  • Cross antennas for surface-enhanced infrared absorption (SEIRA) spectroscopy of chemical moieties
    Patent number: 9372151
    Abstract: A device for Surface Enhanced Infrared Absorption (SEIRA) that includes at least one pair of metallic antennas deposited on a substrate, wherein the pair of metallic antennas are collinear. 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.
