| Abstract: | In order to research the new water-soluble chitosan(CS) antibacterial nano materials,CS was modified by oleic acid as acylation reagents and chloroacetic acid as carboxymethyl reagents,then,the water-soluble oleoyl-carboxymethyl chitosan(OCMCS) were successfully prepared.OCMCS nanoparticles were prepared using an emulsification solvent evaporation method.Escherichia coli and Staphylococcus aureus were investigated for the antibacterial activity of OCMCS nanoparticles.When the concentration was higher than 5... |
