The robust and facile fabrication strategies for surface-enhanced Raman scattering (SERS) active substrates are important for developing practical SERS sensors. Several approaches to creating dielectro-metallic nanostructures have been developed for the SERS application, including the fabrication of metal-shell nanoparticles and bimetallic nanowires. For the practical SERS application, the individual plasmonic nanostructures are required to integrate as one- or two dimensional arrays with highly periodicity and uniformity. However, most attempts recently made have focused on fabricating dielectric-core metal-shell particles. Here, we report a novel SERS platform composed of highly periodic Au /chitosan hybrid nanopatterns. The fabrication strategy employing chitosan nanopatterns will provide reliable reproducibility and good sensitivity for SERS based detection of DNA hybridization. |
