  text: 'We report the enhancement of infrared absorption of chemisorbed carbon monoxide
    on platinum in the gap of plasmonic nanoantennas. Our method is based on the self-assembled
    formation of platinum nanoislands on nanoscopic dipole antenna arrays manufactured
    via electron beam lithography. We employ systematic variations of the plasmonic
    antenna resonance to precisely couple to the molecular stretch vibration of carbon
    monoxide adsorbed on the platinum nanoislands. Ultimately, we reach more than
    1500-fold infrared absorption enhancements, allowing for an ultrasensitive detection
    of a monolayer of chemisorbed carbon monoxide. The developed procedure can be
    adapted to other metal adsorbents and molecular species and could be utilized
    for coverage sensing in surface catalytic reactions. '
