Comparison of Ag, Cu and Zn nanoparticles obtained using Aloe vera extract and gamma ionizing radiation

Abstract

The characteristics of the nanoparticles of silver, copper and zinc obtained from two synthetic routes were investigated. A possible future application of these nanoparticles is as bactericidal agents. The reduction methods were Aloe vera extract and gamma ray irradiation with a dose rate of 0.756 kGy/h and a total dose of 40 kGy from a 60Co-source. The chemical species of the nanoparticles (NPs) obtained by Aloe vera extract were Ag, CuO, and ZnO; while the NPs obtained using gamma irradiation were Ag and Cu2O. The precursor to obtaining the nanoparticles and the route of synthesis define the purity, morphology, crystallinity, and chemical speciation of the metal.

Green Synthesis of Gold and Copper Nanoparticles by Lannea discolor: Characterization and Antibacterial Activity

“…Other uses include enhancing heat transfer liquids, photonic devices, sensors, and electrochemical devices [14,15]. CuNPs, with their unique properties, have gained significant applications in various industries such as cosmetology, agriculture, food, textiles, and construction [16,17]. In several studies, CuNPs providing higher environmental mobility were synthesized using various plant extracts, including Cissus vitiginea [17], Zingiber officinalis and Curcuma longa [18], Brassica oleracea [19], and Hyptis suaveolens (L.) [20].…”
