Dressing materials may inhibit bleeding, protect the wound
from environmental irritants as well as water and electrolyte disturbances,
and prevent invasion of microorganisms.
Even though antibiotics have been greatly improved to deal with the increasing
drug resistance of pathogens, it is also necessary to find advanced
dressing materials which increase the drug resistance of pathogens
effectively
Zinc oxide (ZnO) has attracted wide interest because of its good
photocatalytic activity, high stability, antibacterial property, and
non-toxicity .
It was also reported that ZnO was found not to
be cytotoxic to cultured human dermal fibroblasts .
ZnO nanostructures have many important applications in
biomedical fields, piezoelectric
biosensors, food additives, and catalysis.
Previous studies have demonstrated that ZnO exhibited antimicrobial activities
on a broad spectrum of bacteria.
ZnO nanoparticles exert biocidal effects on bacterial, fungal, and
viral species.
