Reversible phase transfer and fractionation of Au nanoparticles by pH change.
The reversible transfer of Au nanoparticles between water and chloroform phases by pH change was achieved by using a long-chain amine derivative. Further, we demonstrated that the phase transfer method was very effective for the fractionation of Au nanoparticles according to their crystal facet distinction.
