Abstract
•Biosynthesis of AuNPs from leaf extract of L. acidissima is the first report and eco-friendly approach.•The purity of La-AuNPs was confirmed by EDX analysis at 2 KeV, SEM and HR-TEM show the particle size is 100 nm.•Fabric-coated La-AuNPs have antibacterial potential properties.
The present study explored the green synthesis of gold nanoparticles (AuNPs) using aqueous leaf extract of Limonia acidissima as a capping agent and their antibacterial and wound healing properties. The La-AuNPs confirm the color change from straw to ruby red shows an absorption peak at a wavelength of 560 nm in UV–vis spectrophotometer. High-resolution transmission electron microscope (HR-TEM) studies confirm the spherical shape and the average particle size is 100 nm. The synthesized AuNPs showed maximum antibacterial activity against E. coli shows an inhibitory action of 19 mm. In addition, the green synthesized La-AuNPs induced a significant effect of cytotoxicity effect against L929 cell lines, and also cell migration assay showed no toxicity.
