Nano-Enhanced Biopolymers for Antimicrobial Applications

Nanotechnology plays a very important role in biological research due to its small size as well as lower toxicity with their greater efficiency. The natural biopolymers include such as chitosan, cellulose, starch, collagen, gelatin, fibrin, hyaluronic acids, and alginates which are widely distributed in nature. The biopolymeric nanoparticles are developed due to their properties such as biocompatibility, antioxidant, antibacterial, photoprotection, biodegradability, minimal toxicity, and eco-friendliness. Due to these properties and various applications, the nano-based biopolymer attracted in food industry, agricultural domain, biomedicine via drug delivery, antibacterial activity, and slow release of fertilizers. This chapter mainly covers application of nano-based biopolymer as antimicrobial agent. In addition, this chapter also covers the types of biopolymeric nanoparticles, their synthesis, and characterization.
