Abstract
Indian traditional medicinal plants are important sources of phytotherapeutic agents. Plants with antimicrobial properties
have been involved in the treatment of infectious diseases and also, in mitigating the side effects produced by the synthetic
antimicrobial agents. Hence, the present work has been focused on the study the antimicrobial activity of Thespesia populnea
extract-coated nano-zirconium on cotton gauze fabrics. UV–Vis spectroscopy showed the strong peaks produced by Zr
nanoparticle after 200 nm, which indicated that T. populnea-coated Zr nanoparticles would possess antimicrobial activity.
The crystalline nature of the nanoparticles was confirmed by XRD analysis and the smaller size of the nanoparticles about 10
nm was observed using TEM analysis. The antimicrobial activity of T. populnea extract-coated Zr nanoparticles was studied
by well diffusion against pathogens such as E. coli, Bacillus subtilis, Staphylococcus aureus and Pseudomonas aeruginosa
and the Zr nanoparticles showed a high toxicity against the bacterial species studied. The antimicrobial activity suggests
that the synthesized nanoparticles can be used in wounds dressings.
