AbstractNano ZnO(Zinc oxide) as antibacterial agent received many versatile features because of its inexpensive, non toxic and has eco friendly nature. Zinc Oxide nano (ZnOnano) particles are commonly applied in pollutants removal and disinfectants, because of its high chemical stability and poison less characteristics. The addition of metal based particles into polymers is a versatile route to take advantage of their strong antimicrobial properties producing novel biocide materials and allowing a further extension of the range of applications. There are several useful features of Chitosan, such as non-toxicity, hydrophilicity, biocompatibility, biodegradability and antibacterial property which make it as a versatile material in many biomedical applications. The combining of polymer such as Chitosan and ZnOnano particles to form films or hydro gel materials have further advantages such as non aggregated nature and recyclablilty. The proposed approach can stabilise ZnOnano particles in Chitosan matrix by an alkaline solidification process. The fabricated ChitosannanoZnO composite has potential for many-sided applications such as bactericides, polluted water treatment andbiofouling.
