Nanoparticles (NPs) with unique chemical and physical properties can be used for therapeutic purposes because of their strong antimicrobial activates. Nanoparticles have been used as an antimicrobial agents to inhibit microbial growth.
In view of the strong antimicrobial activity of nanoparticles, the biogenic synthesis and leishmanicidal activity of rod-shaped zinc oxide (R-ZnO) nanoparticles was explored using Lilium ledebourii tuber extract.
The ensuing nanoparticles are characterized by UV-visible spectroscopy, X-ray diffraction and transmission electron microscopy and their leishmanicidal activity evaluated against the Leishmania major (L. major) by MTT assay.
The R-ZnO nanoparticles displayed excellent leishmanicidal activity against the L. major as they significantly inhibited the amastigotes. The IC values of R-ZnO nanoparticles being ~ 0.001 mg.mL. R-ZnO nanoparticles can inhibit L. major growth in a dose-dependent manner under in vitro conditions.
A simple, low-cost feasible and eco-friendly procedure was developed for biosynthesis of R-ZnO nanoparticles using natural bioresource that can inhibit human parasite cells growth in a dose-dependent manner under in vitro conditions.

鉴于纳米颗粒具有强大的抗菌活性,本研究利用条叶百合鳞茎提取物探索了棒状氧化锌(R-ZnO)纳米颗粒的生物合成及其对利什曼原虫的杀伤活性。
通过紫外可见光谱、X射线衍射和透射电子显微镜对所得纳米颗粒进行表征,并采用MTT法评估其对硕大利什曼原虫(L. major)的杀利什曼活性。
R-ZnO纳米颗粒对硕大利什曼原虫表现出优异的杀利什曼活性,因为它们能显著抑制无鞭毛体。R-ZnO纳米颗粒的半数抑制浓度(IC)值约为0.001 mg/mL。在体外条件下,R-ZnO纳米颗粒能以剂量依赖的方式抑制硕大利什曼原虫的生长。
开发了一种简单、低成本、可行且环保的方法,利用天然生物资源生物合成R-ZnO纳米颗粒,该纳米颗粒在体外条件下能以剂量依赖的方式抑制人体寄生虫细胞的生长。
