Aloe vera–Based Green Synthesis of Silver Nanoparticles With Characterization, Potent Antibacterial and Antioxidant Properties

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Green synthesis has emerged as a suitable alternative to the traditional method for manufacturing nanoparticles (NPs) as it provides a safer, sustainable, healthy, and environmental path for the NPs synthesis. Silver nanoparticles (AgNPs) were prepared using a green method with locally sourced Aloe vera leaf extract.
