Comparative Antimicrobial Activity of Silver Nanoparticle Synthesized using Lantana camara Leaves

This study explores the use of Lantana camara in the synthesis of silver nanoparticles, with a focus on assessing their antimicrobial properties. The primary objective is to examine the effectiveness of silver nanoparticles produced from Lantana camara leaf extract against various microbial pathogens. The synthesis process involved reacting the leaf extract with a silver nitrate solution, resulting in the formation of silver nanoparticles. These nanoparticles were confirmed through ultraviolet-visible absorption spectroscopy, then analysed using TEM and subsequently tested for antimicrobial activity. The antimicrobial potential was evaluated using the agar well diffusion method against microbes including E. coli, K. pneumonia, S. aureus, and B. subtilis with the inhibition zones indicating antimicrobial efficacy against all the four cultures with a maximum ZOI of 21, 9, 14 and 18mm respectively. The antibacterial activity of the silver nanoparticles (AgNPs) synthesized in this study was compared to that reported in existing literature and found to be comparable, with some instances demonstrating even greater efficacy.
