In the current scenario many researches are done on polymers and their nanocomposites that helps to design and develop new material with distinct properties which can enhance the quality of human life. So such investigations on novel polymers are emerging, since it becomes essential and inevitable in fields of life such as clothing, exterior coatings, food, biotechnology, medicine and so on. Currently need for biodegradable products are increasing day by day. Biodegradable polymers are polymers designed to degrade upon disposal by the action of living organisms into natural bioproducts such as gases, biomass, organic salts and water. Starch and Casein are natural biodegradable polymers with various biological activity. Addition of nano scale fillers allows the modification of physical properties as well as performance of new feature in the polymer matrix. The aim of present study is to prepare starch/casein blend films by solution casting method and its nanocomposite with silver nanoparticles. The prepared polymer and its nanocomposite were characterized by Infrared spectroscopy (FTIR) and UV-Visible spectroscopy. Antibacterial activity of the samples were studied using the agar well/disc diffusion method. Result showed that starch/casein nanocomposite can be used for various biological applications.
