Abstract

Raman scattering from single gold nanostars coated with self-assembled monolayers of 4-mercaptobenzoic acid is observed. The Raman signal can be detected without the need of forming particle aggregates or resonant electronic excitation of the analyte. A total Raman enhancement factor of 107 for individual nanostars is estimated. These features make gold nanostars promising for Raman imaging in cells or cellular membranes. © 2009 American Institute of Physics.
