- Abstract
- A single Au nanoparticle (NP) with a diameter of 5 nm was transferred to the end of a Si-tip through a picking process, and an Ag shell with a controlled thickness was formed on the Au core. By carrying out tip-enhanced Raman scattering (TERS) measurements on biphenyl-4-thiol (BPT) with the Au@Ag NP-tip (overall diameter of 22-60 nm), we confirm that such tips show a plasmonic localfield enhancement which is sufficient for tip-enhanced spectromicroscopy.
