Author(s): Sandhiya Renganathan and *Radha Palaniswamy

Abstract: Green synthesis of silver nanoparticles has an edge over the other nanoparticles for its unique eco-friendly characteristics. Medicinal plants are phenomenally essential for the synthesis of these Nano-sized particles which has numerous advantages in the field of medicine and pharmacology. Origanum majorana leaves are used in the present study for the synthesis which is further extended to analyze its property as an antibacterial and antifungal agent. Both the tender and mature leaves of the plant were used in the study. The silver nanoparticles produced from the leaf of O. majorana has potential antibacterial effect against pathogens like Staphylococcus aureus and Escherichia coli. It proved to be a good antifungal agent also against pathogens like Candida albicans and Aspergillus flavus with this observation, the study was extended towards the application aspect where the nanoparticles were coated over the first aid bandage to analyse its effect. Levels of protection proved that the nanoparticles of O. majorana leaves, both mature and tender, can be used as antibacterial and antifungal protective agent.
