Sensitive support: Assembling plasmonic nanoshells into periodic arrays with nanoscale interparticle gaps gave a substrate on which surface-enhanced (SE) Raman spectroscopy (RS) and infrared absorption (IRA) spectroscopy can be performed simultaneously to enable molecular detection and characterization with high precision and sensitivity. The picture shows an SEM image of the Au nanoshell array and SERS and SEIRA spectra of a p-mercaptoaniline monolayer on the array.
