Gold nanoparticles were successfully synthesized using a green and sustainable approach involving the seed extract of Bryonia laciniosa. The synthesized gold nanoparticles exhibited excellent stability, catalytic potential, and antibacterial activity.
Gold nanoparticles (Au NPs) were synthesized via a green and sustainable approach using the seed extract of Bryonia laciniosa (shivlingi seeds). The prepared AuNPs were characterized by UV-visible spectroscopy, transmission electron microscopy (TEM), Fourier transforms infrared spectroscopy (FTIR), and particle size analysis using DLS. UV-visible and FTIR results elucidated that the prepared Au NPs showed absorption band at 533 nm and signals for biomolecules that were responsible for the stabilization of Au NPs such as phenolic components. The Au NPs were spherical with a diameter of 20-40 nm as revealed by TEM measurements. The synthesized Au NPs demonstrated excellent catalytic potential by reducing 4-nitropenol within 15 min. Furthermore, Au NPs demonstrated substantial antibacterial potency against Bacillus subtilis and Escherichia coli bacteria, with clearance zones of 5 and 16 mm, respectively.(c) 2022 The Author(s).
