Chitosan based films and nanocomposites have receiv-ed great attention in recent times for its desirable antimicrobial, biodegradableand biocompatible attributes combined with natural abundance andeconomical processing. Chitosan is derived from the deacetylation ofchitin (which is naturally found in the exoskeleton of crustaceans) andis made up of glucosamine and N-acetyl glucosamine units linked by β(1–4) glycosidic linkages. Due to its microbicidal and nontoxic nature,chitosan has found diverse range of usage such as in food packaging andpreservation which includes coatings on bread, fruit, vegetable, eggs,and various meat products and in healthcare and biomedical field suchas in drug delivery, wound dressing material, skin grafts and tissueregeneration scaffold [1–5]. The positively charged amino group isinstrumental in interacting with biological membranes and makes it apotent antimicrobial moiety. However, antimicrobial property of
