Recovery of Nanoparticles Made Easy

Here is demonstrated a novel approach to reversible control over nanoparticle (NP) stability, permitting facile recovery for the reuse of inorganic NPs. For the first time, the separation of NPs is achieved by suspending the nanostructures in a background-supporting colloidal fluid, which itself shows a liquid-liquid critical-type phase transition at a temperature T(c) instead of using a normal molecular solvent.
