Synthesis and assembly of topographically complex hybrid materials. (A) Highly ordered double helices are formed using an organic molecule, PEPAu with an aliphatic carbon tail on the N-terminus. (B) By adding chloroauric acid (HAuCl4) to the solution, additional structures were formed in a precipitate. This work has been extended to spherical superstructures (C), including hollow spherical gold nanoparticles templated with structurally modified PEPAu. (A, B) Reprinted with permission from [108].
