1. Fabrication of the gold shells on the silica cores was accomplished using the seeded-growth method, a process which allows for good control of the shell thickness and surface properties.
2. With this method, the APTMS-functionalized silica nanoparticles are initially decorated with colloidal particles of gold (1−3 nm).
3. The gold colloids formed by the reduction of HAuCl4 with THPC have a net negative surface charge,leading to their attachment to the amino groups on the silica
sphere, which are positively charged at neutral pH.
4. In the final step of the formation of the shell, the attached gold nanoseeds
are used to nucleate the growth of a gold overlayer to form the AuNS in the presence of HAuCl4 and the reducing agent, formaldehyde.
5. Figures 1a and 1b show SEM and TEM images, respectively, of the synthesized AuNSs exhibiting a uniform shell layer of ∼20 nm.
6. The gold coating is continuous with topographical roughness on a nanometer scale. 7. 7. The particle size distribution of the AuNSs determined from the SEM images is
shown in Figure 1c, and the associated average diameter is 185 ± 19 nm, which is a value that is consistent with those obtained via TEM and DLS measurement.
