Poly(o-toluidine) hollow spheres with controllable size (see figure) are synthesized in aqueous solution by the droplet template formed by the monomer itself. The size of the hollow spheres and the size of the hole in the surface of each sphere are affected by the concentration of o-toluidine and the molar ratio of initiator to monomer, respectively.
