forms persistent infections through the formation of biofilms that confer resistance to existing antifungal drugs. Biofilm targeting is therefore a promising strategy to combat infections. The WS/ZnO nanohybrids exhibits considerably improved antibiofilm activity and inhibited the biofilm formation by 91%, which is quite better than that for pristine WS, which is only 74%. The physical blend prepared by mixing WS nanosheets and WS/ZnO in the ratio of 70:30 showed an antibiofilm activity of 58%, which was intermediate to that observed for pristine materials. The as-synthesized nanohybrid also demonstrates dose-dependent antifungal activity as calculated using the disc diffusion test. WS/ZnO nanohybrid shows 1.5 times higher activity compared to pristine WS nanosheets suggesting that the nanohybrid materials are more effective as novel antifungal materials.
通过形成生物膜产生对现有抗真菌药物的抗性,从而形成持续性感染。因此,靶向生物膜是对抗感染的一种有前景的策略。WS/ZnO纳米杂化物表现出显著提高的抗生物膜活性,抑制生物膜形成达91%,这比原始WS的74%要好得多。以70:30的比例混合WS纳米片和WS/ZnO制备的物理混合物显示出58%的抗生物膜活性,介于原始材料观察到的活性之间。通过纸片扩散试验计算,合成的纳米杂化物还表现出剂量依赖性抗真菌活性。WS/ZnO纳米杂化物的活性比原始WS纳米片高1.5倍,表明纳米杂化材料作为新型抗真菌材料更有效。
