Description

At the Linfield Symposium the research on silver coated gold nanoparticles tagged SERS will be presented. Gold core nanoparticles were synthesized and coated with a silver shell. These core-shell nanoparticles were tagged with a Surface Enhanced Raman Signal (SERS) tag, 4-aminothiophenol. These tagged particles were monitored for stability and signal enhancement over time. When stability was proven, the tagged particles were coated with a polymer (PAH) and then a lipid bilayer (POPS:LPC). These particles were again monitored for stability and signal strength on the Raman. The overall goal was to synthesize silver coated gold nanoparticles, tag and enhance their Raman signal, and coat them with lipids while keeping the particles at a reasonable small size.
