Squid pen chitosan nanoparticles: small size and high antibacterial activity

Chitosan nanoparticles (CSNs) have widely studied for many potential applications as a bioactive nanomaterial because of their excellent properties, such as quantum size effect, large surface area, high mobility, and high permeability. In this study, various CSNs prepared from squid pen chitosan with different molecular weight (Mw) and degree of deacetylation (DD). The lower Mw and higher DD of initial chitosan used, the smaller size of CSNs...
