Abstract EN
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 single λ-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 of λ-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.
