Nanoscale Gold Rush: new opportunities in Nanogold
In the quest to develop highly stable nanoparticles, N-heterocyclic carbenes (NHC) have emerged as an alternative to thiol-based ligands for stabilizing metal nanoparticles (NPs), as the metal-NHC bond is usually much stronger than the corresponding metal-thiol bond. This should result in more stable NPs which are less susceptible to ligand exchange reactions. Over the last decade an increasing number of NHC-stabilized NPs have been reported and significant effort was made in utilizing these compounds, such as for bioimaging, sensing and heterogeneous catalysis.
This talk will account our efforts to develop carbene-stabilized gold nanoparticles.
