In this work we summarize last achievements of the colloidal synthesis and applications of different amphiphilic nanoparticles, among which are semiconductor, metal and metal oxide materials. All these nanoparticles have been obtained employing polyethylene glycol based stabilizers which provide compatibility with a wide variety of media from nonpolar organics to water. Owing to their versatile solubility, the materials obtained have the ability of spontaneous multiphase transfer. Moreover, they have been shown to permeate through cell membranes avoiding endocytosis which makes them particularly interesting for bio-applications.
