Zinc oxide (ZnO) was biosynthesised from aloe vera plant extract. The aloe vera plant extract was used as a reducing agent in biosynthesis process. Green synthesis method was proposed because it is cost effective and environmentally friendly. ZnO was characterised using SEM, EDX, FTIR, and XRD analyses. The antibacterial property was tested against . The effects of aloe vera volume (2-50) mL, precursor concentration (0.001-0.300) M, reaction time (20 min-48 h), and temperature of the reaction (26-200) °C on ZnO characteristics were investigated and screened using a two-level factorial method. Based on the observation and ANOVA analysis result, precursor concentration was the only significant parameter that affected the production of the ZnO nanoparticles (NPs). The EDX analysis proved the presence of ZnO while the SEM analysis confirmed the average size of ZnO particle size was in the range of (18-618) μm with a rod-shape appearance. The XRD analysis showed that the average crystallite size was 0.452 μm and it was in the hexagonal phase. It was also proven to have antibacterial property against .
氧化锌（ZnO）由芦荟植物提取物生物合成。芦荟植物提取物在生物合成过程中用作还原剂。之所以提出绿色合成方法，是因为它具有成本效益且环保。采用扫描电子显微镜（SEM）、能量散射X射线光谱（EDX）、傅里叶变换红外光谱（FTIR）和X射线衍射（XRD）分析对ZnO进行表征。测试了其对……的抗菌性能。采用二级析因法研究并筛选了芦荟体积（2 - 50）mL、前驱体浓度（0.001 - 0.300）M、反应时间（20分钟 - 48小时）以及反应温度（26 - 200）℃对ZnO特性的影响。基于观察结果和方差分析（ANOVA）结果，前驱体浓度是影响ZnO纳米颗粒（NPs）生成的唯一显著参数。EDX分析证明了ZnO的存在，而SEM分析证实ZnO颗粒的平均尺寸在（18 - 618）μm范围内，呈棒状外观。XRD分析表明平均晶粒尺寸为0.452μm，且处于六方相。还证明了其对……具有抗菌性能。
