Since most of the antibiotics seem to be less sensitive to many organisms, researchers started finding a new potential antimicrobial agent [1]. With this respect, silver and silver-based compounds are having strong bacteriocidal and fungicidal activity [2, 3, 4]. Nanoparticles having larger surface area to volume ratio tend to pose higher antimicrobial activity [5]. Also, Silver has a lower propensity to stimulate microbial resistance than many other antimicrobial agents [1, 6]. Based on these properties, Ag-NPs have been used in wide range of applications such as to prevent infection, in (burn and traumatic) wound dressings, diabetic ulcers, coating of catheters, dental works, scaffold, and medical devices [7, 8]. Green synthesis, a novel green chemical route for producing nanoparticles from plant extracts are having more advantageous than the method of using microbes for nanoparticle synthesis [9]. Tea extract (Camellia sinensis) are effective reducing agents, because of their high polyphenol content are used in nanoparticle (Ag–NPs) synthesis.
