Resumen

     In this seminar I will talk about the importance of the substrate
fabrication and functionalization for surface enhanced Raman spectroscopy
(SERS), and recent efforts at the Van Duyne group to tackle experimental
challenges in two different research projects. First, I will describe the
fabrication of aluminum film-over nanosphere (AlFON) substrates and their
application for deep UV (λex = 229 nm) surface-enhanced resonance Raman
scattering (UVSERRS) as an affordable substrate.[1] Secondly, I will
discuss our progress towards monitoring single electron transfer events at
the single-molecule level with electrochemical surface-enhanced Raman
spectroscopy (EC-SERS). In this project, we aim to correlate the structural
information provided by SERS with electrochemical behavior of rhodamine-6G
(R6G) in non-aqueous conditions at both single- and many-molecule
levels.[2,3]
