The current study demonstrates a sophisticated and environmentally friendly synthesis of zinc oxide nanoparticles (ZnO-NPs) for a range of biological and environmental applications using as a bio-source. At the nanometer scale, a simple aqueous extract from was used to convert Zn into stable elemental zinc (Zn). With an average size of 45.8 nm and a spherical shape, the NPs were stable and pure. The nanoparticles studied here were tested in vitro for bactericide, fungicide, biocompatibility, leishmaniasis, anti-diabetic effect, antioxidant effect, and anti-Alzheimer's effect. According to our results, mediated ZnO-NPs are highly effective against spore-forming fungal strains and MDR bacterial strains. All examined bacterial isolates of UTI (urinary tract infection) were resistant to non-coated antibiotics; however, adding 1% of the produced ZnO-NPs to the treatments increased their bactericidal activity significantly. The NPs also showed dose-dependent cytotoxicity against Leishmania tropica parasites, with an LC50 of 248 μg/mL for promastigote parasites and 251 μg/mL for amastigote parasites. In addition, a significant inhibition of α-glucosidase, α-amylase, butyrylcholinesterase (BChE), and acetylcholinesterase (AChE) was discovered, indicating anti-Alzheimer's and anti-diabetic effects. The biocompatibility of the particles with human red blood cells was also observed. Due to their environmentally friendly production, biological safety, and exceptional physicochemical properties, ZnO-NPs could be used as a new competitor for several biological and environmental applications.
当前的研究展示了一种复杂且环保的氧化锌纳米颗粒(ZnO-NPs)合成方法,该方法使用[生物源名称]作为生物源,用于一系列生物和环境应用。在纳米尺度上,一种来自[生物源名称]的简单水提取物被用于将锌转化为稳定的元素锌(Zn)。这些纳米颗粒平均尺寸为45.8纳米,呈球形,稳定且纯净。本文研究的纳米颗粒在体外进行了杀菌剂、杀真菌剂、生物相容性、利什曼病、抗糖尿病作用、抗氧化作用和抗阿尔茨海默病作用的测试。根据我们的结果,[生物源名称]介导的ZnO-NPs对形成孢子的真菌菌株和耐多药细菌菌株具有高效性。所有检测的尿路感染(UTI)细菌分离株对未包被的抗生素均有抗性;然而,在治疗中添加1%的所制备的ZnO-NPs可显著提高其杀菌活性。这些纳米颗粒对热带利什曼原虫寄生虫也表现出剂量依赖性细胞毒性,前鞭毛体寄生虫的半数致死浓度(LC50)为248μg/mL,无鞭毛体寄生虫的LC50为251μg/mL。此外,还发现对α-葡萄糖苷酶、α-淀粉酶、丁酰胆碱酯酶(BChE)和乙酰胆碱酯酶(AChE)有显著抑制作用,表明具有抗阿尔茨海默病和抗糖尿病作用。还观察到了这些颗粒与人类红细胞的生物相容性。由于其环保的生产方式、生物安全性和优异的物理化学性质,ZnO-NPs可作为多种生物和环境应用的新竞争者。
