An apparatus may include a nonthermal plasma reactor vessel, a gaseous core precursor inlet, a gaseous shell precursor inlet, and a plasma source. The reactor vessel may include a core formation region and a shell formation region downstream of the core formation region. The gaseous core precursor inlet may be upstream of the core formation region and configured to introduce gaseous core precursors to the reactor vessel. The gaseous shell precursor inlet may be downstream of the core formation region, upstream of the shell formation region, and configured to introduce gaseous shell precursors to the reactor vessel. The plasma source may be configured to produce a plasma in the core formation region and the shell formation region. The gaseous core precursors may form negatively-charged core nanoparticles in the core formation region. The gaseous shell precursors may form shells on the core nanoparticles in the shell formation region.
