Preparation nanoparticle by ionic cross-linked emulsified chitosan and its antibacterial activity

Chitosan has antibacterial activity, and preparation of nanoparticles from chitosan was expected to improve its antibacterial properties. Therefore, in order to obtain nanoparticle which can be prepared in large quantities, chitosan was emulsified by different surfactants, and then cross-linked by sodium tripolyphosphate (TPP) to form antibacterial nanoparticles, which can be well dispersible via ionotropic gelation process. The chitosan of 138...
