The response of gold nanorods to digestive ripening has been examined in an aqueous solution in the presence of cetyltrimethylammonium bromide (CTAB). Digestive ripening has proved before to transform a highly size dispersed nanoparticle solutions into a nearly monodisperse ones. Here we observed that nanorods tend to shrink in length and completely transform into nanospheres or atomic Au after enough digestive ripening (DR) time. The concentration of CTAB and gold strongly influence the result of the ripening.
