| dc.description.abstract | This paper deals with Ag, ZnO and Ag-doped ZnO nanoparticles embedded in
chitosan (CS) matrix, prepared by hydrolysis of zinc acetate in isopropanol in the
presence of lithium hydroxide (LiOH) in low temperature conditions.
The nanoparticles embedded in the chitosan matrix were characterised by Xray
diffraction (XRD) and scanning electron microscopy (SEM).
The antimicrobial activity of Ag/CS, ZnO/CS and Ag:ZnO/CS composites with
respect to simple CS polymer was investigated by using the paper disc method on
Mueller-Hinton agar without blood against the Gram-negative bacteria,
Escherichia coli (E. coli) and the Gram-positive bacteria, Staphylococcus aureus
(S. Aureus) on Mueller-Hinton agar with blood. The nanocomposites materials
showed good antimicrobial activity, that recommends them for applications in
medical and food packaging fields. | ro_RO |
