Many functional materials (e.g. catalysts) critically depend on the spatial distribution of surface active sites. However, most spectroscopic measurements are ensemble-based, where reactivity is averaged over millions of nanoparticles. Here, carbene attached to nanoparticle surfaces serves a model system for studying catalytic reactions on single nanoparticles. Article link.
