 Chitosan is a natural biopolymer derived from crustaceans and has been used as an antibacterial agent due to its ability to bind to bacteria and fungi. In this study, researchers investigated the antifungal properties of Chitosan and its derivatives, trimethylchitosan, TMC, and Chitosan nanoparticles against three common fungal pathogens, candida albicans, fusarium solani, and aspergillus niger. They found that Chitosan nanoparticles had greater antifungal activity than the solution form of Chitosan against all three species. Furthermore, they observed that the antifungal activity of Chitosan nanoparticles was dependent on their particle size and zeta potential. Additionally, they found that TMC did not have any antifungal activity against these pathogenic fungi. Overall, this study suggests that Chitosan nanoparticles may be a promising alternative to synthetic antimicrobial agents.
