- Abstract
Starting with a short biography, Schatz then reviews Van Duyne's leading contributions to the discovery and development of SERS as well as pioneering work on localized surface plasmon resonance (LSPR), tip-enhanced Raman scattering (TERS), electrochemical surface-enhanced Raman scattering (SERS)/TERS, and ultrafast nonlinear techniques. SP [ sp 1 SP ] sp The second paper by Moskovits and Piorek is also important, giving a brief history of SERS and its connection with localized surface plasmon excitation. The resulting particle-tipped needles allow dual enhancement of the Raman signals from microdroplets of low concentration analytes by combining analyte enrichment through solvent evaporation and plasmonic SERS enhancement. They discuss the challenges and perspectives in designing and synthesizing nanogap structures that deliver strong, reproducible, and reliable SERS signals for quantitative SERS analysis. SP [ sp 11 SP ] sp In the work presented by Xu, Bell, et al., a SERS-active superhydrophobic (SHP) tip is constructed by an adsorbing a layer of densely packed and uniform plasmonic nanoparticles onto a hydrophilic tip. Also, by utilizing the LRSP mode, electrochemical reactions on the Pt surface could be protected from any nanoscale effects, which is advantageous over conventional SERS. SP [ sp 16 SP ] sp Murakoshi et al. carry out electrochemical SERS measurements to clarify the detailed molecular behavior in the strong coupling regime.
