Through the current comparative study, colloidal silver nanoparticles (AgNPs) were synthesized with various morphologies and sizes using Prunus domestica (P-dom) extract and sodium citrate as green and chemical reducing agents, respectively. AgNPs were synthesized employing different concentrations of the reducing agents in an aqueous solution at various pH values (3-10) and temperatures (25-85 degrees C). The UV-visible absorption spectrum indicated characteristic SPR peaks of AgNPs at 380-450 nm. Fourier transform infrared spectroscopy revealed aqueous-soluble polyols (such as glycosides, phenols, and flavanols) participation in Ag ions reduction to the corresponding AgNPs at various pH values. The crystallinity of AgNPs was detected by an X-ray diffractometer. Different morphologies (polygonal, oval, and spherical) of the AgNPs with varying pH values were confirmed conducting transmission electron microscopy (TEM). Average particle sizes of 16-50 nm were determined using scanning electron microscopy, TEM, and dynamic light scattering assessments for AgNPs synthesized at various reaction conditions. This study is a demonstration for a facile, cheap, and eco-friendly stimuli-sensitive preparation of the AgNPs. (C) 2020 The Society of Powder Technology Japan.
