Expanding the potential of gold nanoparticles for a range of uses requires methods to stabilize the clusters and control their size. Researchers at KAUST reveal how simple organic citrate ions, derived from readily available citric acid, can interact with the gold atoms to yield the stable nanoparticles needed for further research.
