Abstract
It is shown that alkane thiol-capped gold nanoparticles can be dissolved in supercritical ethane. Importantly, the solubility was found to be dependen t on the core diameter thus allowing separation by size. Nanoparticles with a core diameter less than 1.7 mn were soluble in the supercritical fluid.
