DEVELOPMENT OF SILVER NANODOTS ON POLYSTYRENE FILM

Polystyrene(PS) is a very widely used plastic in industries like food packaging. Polystyrene(PS) is used in the food packaging industry also because it insulates better, keeps food fresher for a longer duration of time and it costs lesser than other alternatives.This paper is focused on building a method to develop well defined silver nanodots of different composition (0.4,0.6,1.2%w/v) on polystyrene film. The antimicrobial activity towards bacteria is checked using experimentation as compared to the plane polystyrene film. It has been found in the literature that such materials(in this case silver nanodots) delay the growth of Pseudomonas fluorescens and Staphylococcus aureus.
