Green synthesis of silver nanoparticles by employing the Allium fistulosum, Tabernaemontana divaricate and Basella alba leaf extracts for antimicrobial applications

Abstract

Nanoparticles produced from biological sources are gaining a lot of attention these days, and they have a wide spectrum of uses. The fact that it is both environmentally benignis the key reason for its widespread popularity. Our current study uses a green approach to describe the biological production and characterisation of silver nanoparticles made from a conventional leaf extract. The antibacterial and antidiabetic performance of silver nanoparticles prepared with plant extracts such as Tabernaemontana divaricate, Basella alba, and Allium fistulosum is also assessed in this study. Scanning Electron Microscopy (SEM), and Transmission Electron Microscope (TEM) was utilized to characterise the shape and morphology of produced silver nanoparticles. Silver nanoparticles with sizes of 40 nm, 50 nm and 57 nm were observed to have a solid block-like, rod-like structure. AgNPs show bactericidal action towards both gram-positive and -negative microbes, according to in vitro investigations. Both antidiabetic and antioxidant activity suggest that silver nanoparticle has good ability to inhibit enzymes so it could act as alternative for the conventional drug.
