title: Synthesis and characterization of gold nanoparticles based on low generational triethylene glycol-polyamidoamine dendrimers.
abstract: Low generational polyamidoamine (PAMAM) dendrimers with triethylene glycol (TEG) core and ester groups at the surface have been synthesized and investigated as templates for preparation of gold nanoparticles (AuNPs), by reducing chloroauric acid (HAuCl4) with potassium borohydride (KBH4) in N,N-dimethylformamide (DMF). UV-vis absorption spectroscopy, fourier transform infrared (FT-IR) spectroscopy, dynamic light scattering (DLS), and transmission electron microscopy (TEM) were used to confirm the formation of AuNPs. Stable gold nanoparticles with particle size around 10 nm were obtained and the interaction between the dendrimers and Au moieties is discussed.
