A simple and reliable method is described to produce inorganic nanoparticles functionalized asymmetrically with domains of hydrophobic hydrophilic ligands on their respective hemispheres. These amphiphilic, Janus-type particles form spontaneously by a thermodynamically controlled process, in which the particle cores two competing assemble at interface between immiscible liquids reduce interfacial energy. The asymmetric surface chemistry resulting from this process was confirmed using contact...

We describe the spontaneous incorporation of amphiphilic gold nanoparticles (Au NPs) into walls surfactant vesicles. Au NPs were functionalized with mixed monolayers hydrophilic (deprotonated mercaptoundecanoic acid, MUA) and hydrophobic (octadecanethiol, ODT) ligands, which are known to redistribute dynamically on NP surface in response changes local environment. When preformed vesicles, ODT ligands interact favorably core bilayer structure guide vesicle walls. Unlike previous strategies...
