A general Ostwald ripening process combined with colloidal soft‐matter self‐assembly has been developed for coaxing the solid nanoparticle rods into the tubular mesocrystals: self‐assembled ZnO microtubules with surface grafting of nanorods, in which the polyelectrolyte is exploited to tailor the forces between the colloidal ZnO nanoparticles and manipulate nanoparticle self‐assembly. The strategy presented here can readily be extended to other soft‐matter chemical systems that afford colloidal processing.
