Abstract

The capability of cucurbit[n]uril to align gold nanorods, leading to optical coupling into the infrared region, is shown. Cryo-TEM and tomographic imaging confirm the presence of aligned Au nanorods. Full electromagnetic simulations, which support the observed plasmonic modes and predict large enhancements in the inter-particle junction, are performed. This construct is then further utilized for surface enhanced Raman spectroscopy.
