Paper Abstract

Gold nanoparticles (GNPs) have been synthesized by a seed-mediated growth method. Hexadecyltrimethylammonium bromide (CTAB) was used as a surfactant for both the seed formation and the anisotropic crystals growth. Anisotropic GNPs of various sizes, shapes and aspect ratios were obtained by using different amounts of silver ions, temperatures and durations of growth as parameters of the process. The SEM images and the Localized Surface Plasmon Resonance (LSPR) bands in the UV-Vis of the anisotropic GNPs have been studied. Preliminary sensing experiments have been carried out as well. This work has proved again the high sensitivity of the synthesis with respect to the conditions of reaction.
