Design, Synthesis, and Optimization of Silver Nanoparticles Using an Artocarpus heterophyllus Lam. Leaf Extract and Its Antibacterial Application

In this study, the synthesis of nanoparticles and their biological evaluation were carried out. A green synthetic approach synthesized silver nanoparticles (AHAgNPs) using an Artocarpus heterophyllus leaf extract. Parameter optimization was performed using Design Expert Ver. 13. The effects of variables like the concentration on the response, particle size, and entrapment efficiency of synthesized AHAgNPs were monitored via analysis of variance. The optimized AgNPs were characterized using ultraviolet–visible spectroscopy and Fourier transform infrared spectroscopy. Scanning electron microscopy and transmission electron microscopy were used to determine the size and shape of nanoparticles. In vitro, antioxidant and antimicrobial potential were determined using standard protocols. The optimized nanoparticles were spherical, with an average 100–110 nm particle diameter. The synthesized nanoparticles showed effective
