Abstract
Chitosan has attracted substantial attention in biomedicine and nanomaterials fields because of its excellent properties, such as biocompatibility, biodegradability, non-toxicity, and antimicrobial properties. Recently, the synthesis of chitosan nanoparticles has received great attention due to its nanometer size and large surface area that will exert substantial and new modification to its properties (high reactivity, improved mechanical properties, etc.) which are crucial for advanced applications. Modification of chitosan nanoparticle with metal oxides can extend its application in various fields. This review highlights the recent advances on synthesis methods and characteristic of chitosan-metal oxides nanoparticles systematically. In addition, the application of chitosan-metal oxides nanoparticle in water treatment as adsorbent, antibacterial agent, and photocatalyst are discussed comprehensively.
Keywords: Chitosan, metal oxides, nanoparticles, synthesis, anti-bacterial
