Abstract

In nanobiotechnology, synthesizing metal nanoparticles (NPs) using plant extracts has recently been increasing because of eco-friendly and low-cost methods. For this work, zinc oxide nanoparticles (ZnO NPs) have been synthesized by biosynthesis process using water hyacinth extracts (WHE). The water hyacinth (WH) was chosen because the WH is fast-growing and the most toxic aquatic plant in the world. Therefore, this work aims to apply these WHE to be a precursor in the biosynthesis of ZnO NPs (ZnOBio-NPs) based on the research of a sustainable environment. The ZnO NPs synthesized by the WHE were investigated for their antibacterial and photocatalytic activities. An UV-Vis spectrum showed a specific absorbance peak around 362 nm with an average band gap of 3.22 eV. As the result, TEM analysis revealed a triangle structure with an average size of about 64.05 nm. The peaks of XRD analysis show a hexagonal wurtzite structure. The ZnO NPs synthesized by the WHE showed higher antibacterial activity against S. aureus better than E. coli. It is interesting to note that the ZnOBio-NPs synthesized from the WHE can have an anti P. acnes (JB7) with a minimum inhibitory concentration (MIC) and a minimum bactericidal concentration (MBC) equal to 50 µg∙mL‒1 and 200 µg∙mL‒1, respectively. In addition, the ZnOBio-NPs also can effectively remove more than 90% of the malachite green within 180 minutes with extremely high reuse.

利用风信子提取物生物合成氧化锌纳米颗粒：表征、抗菌和染料去除评估

在纳米生物技术领域，利用植物萃取物合成金属纳米粒子（NPs）的方法因其生态友好和成本低廉而越来越多。在这项工作中，利用生物合成工艺，使用水葫芦提取物（WHE）合成了氧化锌纳米粒子（ZnO NPs）。之所以选择布袋莲（WHE），是因为布袋莲生长迅速，是世界上毒性最强的水生植物。因此，这项工作旨在基于可持续环境研究，将这些水葫芦提取物用作生物合成氧化锌纳米粒子（ZnOBio-NPs）的前体。研究人员对通过 WHE 合成的 ZnO NPs 进行了抗菌和光催化活性研究。紫外可见光谱显示，在 362 纳米附近有一个特定的吸光峰，平均带隙为 3.22 eV。结果，TEM 分析显示出平均尺寸约为 64.05 nm 的三角形结构。XRD 分析的峰值显示出六方菱面体结构。通过 WHE 合成的 ZnO NPs 对金黄色葡萄球菌的抗菌活性高于对大肠杆菌的抗菌活性。值得注意的是，由 WHE 合成的 ZnOBio-NPs 对痤疮丙酸杆菌（JB7）的最低抑菌浓度（MIC）和最低杀菌浓度（MBC）分别为 50 µg∙mL-1 和 200 µg∙mL-1。此外，ZnOBio-NPs 还能在 180 分钟内有效去除 90% 以上的孔雀石绿，重复利用率极高。
