Abstract

The emerging need for water contamination and antibiotic-resistant microbes calls for environmentally friendly, multi-functional nanomaterials. Vacancy-rich- Zinc Oxide Nanoparticles (UZO NPs) were green-synthesized in the present research using ethanolic extract of Urtica ardens, a Himalayan medicinal plant. The nanoparticles were analyzed by UV–Vis, XRD, FTIR, FE-SEM, HRTEM, EDX, EPR and XPS demonstrating hexagonal ZnO with 37.18 nm crystallite size and spherical-to-rod morphologies(50–90 nm). FTIR and XPS Confirmed phytochemicals facilitating reduction and stabilization. UZO NPs exhibited antibacterial activities against MRSA and Citrobacter and 94.8 % degradation of malachite green within 60 min. The study demonstrates their dual antimicrobial and photocatalytic potential for biomedical and wastewater applications.

来自荨麻叶子的生物氧化锌纳米颗粒：一种可持续的对抗细菌和降解污染物的途径

对水污染和耐抗生素微生物的新需求要求对环境友好的多功能纳米材料。利用喜马拉雅药用植物荨麻的乙醇提取物，绿色合成了富空位氧化锌纳米颗粒（UZO NPs）。通过UV-Vis、XRD、FTIR、FE-SEM、HRTEM、EDX、EPR和XPS等手段对纳米颗粒进行了分析，结果表明ZnO为六方晶，晶粒尺寸为37.18 nm，球形-棒状（50 ~ 90 nm）。经FTIR和XPS证实的植物化学物质有助于还原和稳定。UZO NPs对MRSA和柠檬酸杆菌具有抗菌活性，60 min内对孔雀石绿的降解率为94.8%。该研究证明了它们在生物医学和废水处理方面的双重抗菌和光催化潜力。
