pH Dependence of the Size and Shape of the Gold Nanoparticles Prepared by Peptides

Article Preview

Abstract:

The size and shape of gold nanoparticles controlled by pH was studied in the reacted solutions containing peptides (NH₂-Leu-Aib-Trp-Ome) as reducing agent. The resulting gold nanostructures were characterized by transmission electron microscopy (TEM), XRD and UV-vis-NIR spectra. Different shape of gold nanoparticles such as spheres, multipod and branch were prepared by changing the pH of solution. The resulting gold nanostructures may be have potential applications in the Surface Enhanced Raman Spectroscopy (SERS) and NIR-absorbing filters and coatings.
