Outline of Final Research Achievements

The goal of this grant was to prepare and test stable gold nanoparticles for potential biosensing applications. We have prepared new gold nanoparticles that were protected by carboxylate-functionalized N-heterocyclic carbenes (NHCs) to be water-souble. The resulting gold particles were stable in the presence of electrolytes and gave photoacoustic signals. In addition, we successfully increased stability of gold nanoparticles against thiols by employing bidentate NHC ligands functionalized with long alkyl chains.
