Abstract
The disclosure provides methods of synthesizing non-spherical nanostructures. One embodiment has steps of providing a solution of nanoparticles (NPs) wherein each of the NPs comprises a non-spherical NP that includes gold and a surfactant coating covering the non-spherical NP; mixing the NPs and a pH modifier solution making a pH-modified solution of NPs having a pH within a predefined pH range; and adding a silica precursor solution to the solution of nanoparticles at a constant rate for at least one (1) minute to provide a homogeneous silica solution of NPs. Another embodiment has steps of providing a solution of NPs wherein each of the NPs comprises a non-spherical NP that includes gold and a surfactant coating covering the non-spherical NP; and adding a silica precursor solution to the solution of nanoparticles at a constant rate for at least one (1) minute to provide a homogeneous silica solution of NPs.
