Assessment of long-term stability in silver nanoparticles generated by gamma radiation
A modified electrolytic method that employed the suspension of silver ions (Ag+) and subsequent exposure to gamma radiation at doses of 10, 25, 50, and 70 kGy (kGy) formed the silver nanoparticles (AgNPs). The stability of the AgNPs was monitored over a period of 12 months using UV Vis Spectrophotometry (UV–Vis), Transmission electron microscope (TEM) and Dynamic light scattering (DLS). In particular, AgNPs irradiated at 10 kGy exhibited the most favorable stability of the samples tested, with the additional advantage of requiring less energy for production due to the lower dose employed.
