Gold nanoparticles from 2.5 to 5 nm sizes have also been prepared by using a biphasic Winsor II [126] (a water-in-oil microemulsion that is in equilibrium with the excess water phase) type microemulsion of diethyl ether/AOT/water. The surfactant, AOT, performs the dual role of forming a microemulsion and the transferring of charged metal ions from the aqueous to organic phase. This provides gold nanoparticles, which are readily dispersed in the nonpolar phase.

We shall first present the use of fluorous chemistry with gold nanoparticles. To transfer gold nanoparticles from an aqueous to a perfluorohexane medium, we first prepared a hydrosol containing gold nanoparticles by the reduction of chloroaurate ions (0.55 mL of 25 mM aqueous solution) with partially...
