Among Si-based nanostructures, silica nanowires are gaining a great scientific and technological interest due to their potential applications such as new electronic devices, biosensors, and nanoscale optical devices. Furthermore, their chemical and physical properties, and so their performances in devices, can be enhanced if embedded or decorated on surface by metal nanoparticles (NPs) due to local plasmonic effects. In fact, properties such as surface-enhanced Raman spectroscopy (SERS) and optical wave guiding of the silica nanowires gain enormous benefit from the presence of the metal NPs. In particular, SERS effects in metal NPs/silica nanowires are extremely promising for diagnostics with rapid screening. Examples include identification of cancer malignancies and classification in oncology research and monitoring of drug recipient interaction in pharmaceuticals. The majority of single-molecule …
