Abstract. In this study, the authors developed polygalacturonic acid-stabilized silver nanoparticles (AgNPs) and assessed their physicochemical properties and biological activities. Silver nanoparticles were synthesized through the reduction of silver ions in alkaline solutions of polygalacturonic acid. Spherical particles approximately 90 nm in size were observed using atomic force microscopy, with spherical AgNPs embedded as registered by scanning electron microscopy (SEM). Analysis by SEM revealed a Log-normal distribution with the most probable AgNP size ranging from 10 to 20 nm. The size of silver nanocrystals estimated by X-ray diffraction fell within the range determined by SEM. Fourier-transform infrared spectra indicated bidentate bridging between carboxylate groups of polygalacturonic acid and silver atoms on the AgNP surface, as well as the strengthening of hydrogen bonds in the nanobiocomposites. The antibacterial activity of the resulting nanocomposite samples was also investigated.
