Plant-mediated synthesis of nanoparticles exhibits great potential to minimize the generation of chemical waste through the utilization of non-toxic precursors. In this research work, we report the synthesis of magnesium oxide (MgO) and cobalt oxide (CoO) nanoparticles through a green approach using leaves extract, their surface modification by polyaniline (PANI), and antifungal properties against . Textural and structural characterization of modified and unmodified metal oxide nanoparticles were evaluated using FT-IR, SEM, and XRD. The optimal conditions for inhibition of were achieved by varying nanoparticles' concentration and time exposure. Results demonstrate that PANI/MgO nanoparticles were superior in function relative to PANI/CoO nanoparticles to control the growth rate of at optimal conditions (time exposure of 72 h and nanoparticles concentration of 24 mM). A percentage decrease of 73.2% and 65.1% in fungal growth was observed using PANI/MgO and PANI/CoO nanoparticles, respectively, which was higher than the unmodified metal oxide nanoparticles (67.5% and 63.2%).
植物介导的纳米颗粒合成通过使用无毒前驱体，在最大限度减少化学废物产生方面展现出巨大潜力。在这项研究工作中，我们报告了通过绿色方法利用树叶提取物合成氧化镁（MgO）和氧化钴（CoO）纳米颗粒，用聚苯胺（PANI）对其进行表面改性，以及对[具体真菌名称未给出]的抗真菌特性。使用傅里叶变换红外光谱（FT-IR）、扫描电子显微镜（SEM）和X射线衍射（XRD）对改性和未改性金属氧化物纳米颗粒的结构和形貌进行了表征。通过改变纳米颗粒浓度和暴露时间实现了对[具体真菌名称未给出]抑制的最佳条件。结果表明，在最佳条件下（暴露时间72小时和纳米颗粒浓度24 mM），聚苯胺/氧化镁纳米颗粒在控制[具体真菌名称未给出]生长速率方面的功能优于聚苯胺/氧化钴纳米颗粒。使用聚苯胺/氧化镁和聚苯胺/氧化钴纳米颗粒时，真菌生长分别下降了73.2%和65.1%，高于未改性金属氧化物纳米颗粒（67.5%和63.2%）。
