Enhanced Raman Scattering

Raman scattering signals can be enhanced by several orders of magnitude on surface-enhanced Raman scattering (SERS) substrates made from noble metal nanostructures. Some SERS substrates are even able to detect single-molecule Raman signals. A novel silver nanobud (AgNB) substrate with superior SERS activity was fabricated with a solid-state ionics method. The AgNB substrate was formed by tightly collocated unidirectional 100 nm size silver buds, presenting a highly rough surface topography. Distinct SERS signals of singleλ-DNA molecules in water were detected on AgNB substrates. AgNB substrates were compared with disordered silver nanowire (AgNW) substrates manufactured by the same method through the SERS detection ofλ-DNA solutions. This original AgNB substrate provides a reliable approach towards trace analysis of biomacromolecules and promotes the utilization of the SERS technique in biomedical research.

ABSTRACTAssembly of nanowires into ordered macroscopic structures has attracted great scientific interests in the past decade. In this work, we report a rapid low-cost scalable oil-water interfacial self assembly process for fabricating aligned Ag nanowires (AgNWs) films on solid substrates. This process is much simpler than the traditional Langmuir-Blodgett (LB) techniques and allows the assembly of one–dimensional Ag nanowires onto any solid substrates without extra pretreatment of the surface of silver nanowires or the solid substrate. The present aligned AgNW films can serve as robust surface-enhanced Raman scattering (SERS) sensors for chemical and bimolecular detection with improved spectra quality and demonstrated uniformity of SERS signal using R6G dye as probe.
