Surface-Enhanced Vibrational Spectroscopy of Adsorbates on Microemulsion Synthesized Gold Nanoparticles

Abstract: Very small (<10 nm) monodisperse gold nanoparticles (AuNPs) coated with a monolayer of decanethiol were prepared and their surface-enhanced infrared absorption (SEIRA) spectra were measured in the transmission mode. The AuNPs were prepared by the borohydride reduction of HAuCl(4) inside reverse micelles that were made by adding water to a hexane solution of sodium bis(2-ethylhexyl)sulfosuccinate (AOT). The gold nanoparticles were then stabilized by the addition of decanethiol. Subsequent addition of p-nitrothi… Show more

“…Some approaches have been reported on the development of shared substrates for SERS and SEIRS sensing, , indeed more versatile and simple to integrate in a lab-on-a-chip architecture. Examples include arrays of gold nanoshells, , self-assembled microemulsions, self-assembled pulsed laser deposited gold nanoparticles clusters, sputtered thin-film gold electrodes, near-field coupled silver nanowires, electrochemically treated copper surfaces, and silver–nanoparticles clusters . These nanostructures feature broad LSPRs from the visible to the IR, thus being effective for plasmon-enhanced Raman and IR spectroscopy.…”
