We created these novel nanoparticles via free radical polymerization of styrene encapsulated within the hydrophobic interior of a unimolecular micelle (UM) in water. The resultant particles contain mono-disperse polystyrenes with active free radicals. The livingness of the particles was verified by the reaction with radical scavengers and their capability to initiate further polymerization of either water-insoluble or water-soluble monomers. This creation of LNPs is unprecedented and opens a new technique for polymer synthesis using particle initiators. ?
