The interactions and self-assembly of nanoparticles are often driven by thiol ligands bound to the nanoparticle cores. Recent study has demonstrated that the equilibrium between bound and free thiols in the nanoparticle suspension can alter the core-ligand coverage. Researchers from University of Chicago and University of Illinois at Chicago combined MD simulations and X-ray surface scattering techniques to reveal the impact of free thiols on the self-assembly of Au nanoparticles at the air-water interface.
