Surface enhanced Raman scattering of dendritic Ag nanostructures grown with anodic aluminium oxide

Abstract

We present the application of newly developed Ag nanodendrites (Ag-ND) grown together with anodic aluminium oxide for surface-enhanced Raman scattering (SERS). The Ag-ND yield very pronounced SERS using a self-assembled monolayer (SAM). This is confirmed by simulations showing hot spots in the electromagnetic field at the surfaces of the Ag-ND. SERS measurements reusing Ag-ND demonstrate its long-term stability even after one year.
