Janus particles are synthesized from biphasic emulsions in which the size and shape of particle are determined by the volume ratio and the interfacial tension between the three phases including the suspending medium. By the removal of free or physically adsorbed surfactants from the biphasic particles, mono-patch particles were produced. We demonstrate the spontaneous assembly of these mono-patch particles into dumbbell or micelles through a site-selective hydrophobic interaction. Futhermore, we have functionalized patches with DNA and assembled DNA-coated mono-patch particles into various structures including clusters and wires.
