We report the use of reverse PS-b-P2VP diblock co-polymer micelles as true nanoscale-sized reactor vessels for the synthesize ZnO nanoparticles. Moreover, high spatial resolution Z-contrast imaging and EDX spectroscopy techniques were used to confirm the segregation of the Zn-cation to the core of the loaded micelles. Determining the chemical distribution with high nanoscale spatial resolution powerfully complements the less direct characterization by AFM, DLS and FTIR.
