Chitosan with the addition of zeolite and ZnO nanoparticles as a new antibacterial agent

Chitosan/zeolite/ZnO nanocomposites with different contents of components were obtained using the Taguchi method. Based on the conducted studies, optimal conditions for the synthesis of the nanocomposite (7.5 mg/mL chitosan, 0.2 mg/mL zeolite and 9 mg/mL ZnO) with the best antibacterial properties (no growth of S. mutans) were established. Spectroscopic, microscopic, thermal, and antibacterial methods were used to characterize the nanocomposite and its components in relation to S. mutans biofilm. The chitosan/zeolite/ZnO nanocomposite can be used as an effective antibacterial compound in various applications due to its structural and antibacterial properties.
