Bioengineered silver nanoparticles using Brassica oleracea sub sp. botrytis (L.) for enhanced antibacterial activity

Abstract

The green methodologies of nanoparticles with plant extracts have received an increase of interest. Silver nanoparticles (Ag NPs) have been utilized in a many of applications in the last few decades. The current study presents the synthesis of Ag NPs with aqueous extract of Brassica oleracea sub sp. botrytis (L.) as a stabilizing agent. UV-visible spectroscopy, FTIR, XRD, SEM, TEM, and EDAX analysis were performed to study the synthesized Ag NPs. The synthesized Ag NPs have been measured with dynamic light scattering (DLS), the average size and charge were discovered to be 81.62 ± 1.14 nm and -11.3 ± 2.51 mV, respectively. Furthermore, as-formed AgNPs shown strong antibacterial activity against the Gram-positive bacteria (Staphylococcus aureus). According to the results of this investigation, green synthesized Ag NPs with Brassica oleracea sub sp. botrytis (L.) may be used in biomedicine as a replacement agent for biological applications.
