Giving directions : Microspheres are decorated with a defined number of Au nanodots by using O 2 ‐plasma‐etched colloidal crystals as masks for the deposition of Au vapor (see picture). The Au nanodots deposited on the spheres might be considered as nanoscale analogues of sp‐hybridized atomic orbitals, which may be used to spatially direct the association of spheres to generate hierarchical “supraparticles”.
