Recent trends in green synthesis of silver, gold, and zinc oxide nanoparticles and their application in nanosciences and toxicity: a review

In the recent past, nanoparticles (NPs) have gained the attention of researchers in diverse fields, including chemistry, physics, agriculture, environmental engineering, biological sciences, and material sciences. It has applications in the catalytic process, food chemistry, electronic devices, agroindustry, industrial products, environmental engineering, cancer therapeutics, wastewater treatment, and surface coating. The data for plant-based synthesis and applications of silver (AgO), gold (AuO), and zinc oxide (ZnO) NPs are scattered and need to be gathered. Therefore, this review is designed to assemble the recent advancement in the plant-based synthesis of AgO, AuO, and ZnO-NPs, and the toxicity results of these NPs have been discussed in detail. So herein, we streamlined the data of plant-based synthesis, application, and toxic effects of AgO, AuO, and ZnO-NPs.
