Claim:
1. A method for preparing a composition comprising a polar solvent comprising a nanoparticle, the method comprising: irradiating a biphasic mixture, the biphasic mixture comprising a polar solvent and a non-polar solvent, the polar solvent and the non-polar solvent being immiscible in each other; wherein, prior to irradiation, the polar solvent comprises a hydrophilic surfactant, the hydrophilic surfactant comprising a moiety reactive with a surface of the nanoparticle or a moiety that becomes reactive with a surface of the nanoparticle during irradiation of the biphasic mixture; wherein, prior to irradiation, the non-polar solvent comprises the nanoparticle; and wherein irradiating the biphasic mixture induces a reaction between the nanoparticle and the reactive moiety of the hydrophilic surfactant, which reaction mediates transfer of the nanoparticle from the nonpolar solvent to the polar solvent.
