  • Compositions for surface enhanced infrared absorption spectra and methods of using same
    Publication number: 20100022020
    Abstract: A composition comprising a substrate and at least one adsorbate associated with the substrate wherein the composition has an enhanced infrared absorption spectra. A method comprising tuning a nanoparticle to display a plasmon resonance in the infrared, associating an adsorbate with the nanoparticle to form an adsorbate associated nanoparticle, and aggregating the adsorbate associated nanoparticle. A method of preparing a SERS-SEIRA composition comprising fabricating a nanoparticle substrate, functionalizing the nanoparticle substrate to form a functionalized substrate, dispersing the functionalized substrate in solution to form a dispersed functionalized substrate, and associating the dispersed functionalized substrate with a medium.
