Abstract: Silver NPs were prepared by green chemical approach. The prepared Ag NPs were characterised using XRD, HRTEM and EDAX analysis. The composite film containing PCL with various concentration (0.1, 0.5, 1.0, and 1.5 wt%) of silver NPs was prepared by solution casting method. Further the composite film exhibited strong antibacterial activity against pathogenic micro-organisms B. cereus, Bacillus pumilius, Bacillus subtilis, Clostridium perfringens and Pseudomonas aeruginosa. The enhanced properties attributed due to the incorporation of Ag into PCL matrix.

Keywords: silver NPs; PCL; solution casting; antibacterial; food packaging; composite film; MTT assay.
