  In this study, we are going to report a simple procedure to prepare and assemble noble metal nanoparticle chains using in situ synthesis of dicarboxylic acid (tartaric acid). The objective of this study is to investigate the effect of tartaric acid on silver and gold Nanoparticles (NPs). To address this issue, the optical properties, the morphology of silver, gold nanoparticles and their assemblies were investigated by Ultraviolet–Visible (UV-Vis) spectroscopy and Transmission Electron Microscopy (TEM). In addition, Fourier-Transform Infrared (FTIR) was also used to assure the formation of metal nanoparticles assemblies by means of esterification reaction. Gold and silver NPs colloids showed the typical local surface Plasmon resonance of isolated NPs with a symmetric absorption curve. This symmetry did not hold after the addition of the cross link. Moreover, two Plasmon.. Read More»
