This Project Grant award from the National Science Foundation (NSF) under the Mathematical and Physical Sciences Federal Grant Program (CFDA 47.049) supports research to enhance the stability and performance of colloidal gold nanoparticles. Professor Richard Brutchey of the University of Southern California, in collaboration with Professors Elad Gross and Uri Banin of the Hebrew University of Jerusalem, will investigate the use of N-heterocyclic carbenes (NHCs) as a more durable alternative to traditional thiol-based ligands for coating gold nanoparticle surfaces. The $353,549 award will fund experimental studies to quantify the thermodynamics of NHC binding to gold nanoparticles and characterize their interaction with distinct gold nanoparticle facets at the atomic scale. The findings are expected to enable the rational design of more stable gold nanoparticle systems for targeted applications in medical diagnostics, cancer therapies, and chemical catalysis. No sub-awards are planned under this grant, which has an award date of July 1, 2025 and an ultimate completion date of June 30, 2028.
