One-Pot Synthesis of Nucleoside-Templated Fluorescent Silver Nanoparticles and Gold Nanoparticles.

ABSTRACT: In this study, a simple one-pot method was proposed to synthesize water-soluble nucleoside-templated fluorescent silver nanoparticles (Ag NPs) and gold nanoparticles (Au NPs). The nucleoside-templated fluorescent Ag NPs and Au NPs were further characterized by transmission electron microscopy (TEM), Fourier transform infrared spectroscopy (FTIR), and fluorescence spectroscopy (FLS). The effects of the molar ratio of reactants, reaction environment, and nucleotides on the synthesis of Ag NPs and Au NPs were also discussed. The results showed that nucleoside and ascorbic acid acted as a stabilizer and reductant, respectively, in the synthesis of Ag NPs and Au NPs, while citrate buffer acted as both a pH regulator and reductant. The synthesized nucleoside-templated fluorescent Ag NPs and Au NPs have good fluorescence stability and easy water solubility. In this study, a simple one-pot method was proposed to synthesize water-soluble nucleoside-templated fluorescent silver nanoparticles (Ag NPs) and gold nanoparticles (Au NPs).
