“Stainless” gold nanorods: preserving shape, optical properties, and SERS activity in oxidative environment
One of the main limitations to the application of gold nanorods (Au NRs) as surface-
enhanced Raman scattering (SERS) probes for in situ monitoring of chemical processes is
their instability in oxidative environments. Oxidation induces progressive anisotropic
shortening of the NRs, which are eventually dissolved once this process has been
completed. This paper compares two types of Au NRs, obtained through different routes and
characterized by similar aspect ratios but different sizes. The key factors influencing the …
