Abstract

The aim of this study was to synthesize Zinc oxide (ZnO) and magnetite ıron oxide (Fe3O4) nanoparticles utilizing a precipitation method, employing plant extracts from Ocimum basilica(1), Cinnamomum zeylanicum(2), Lactarius salmonicolor(3) and Paeonia kesrouanensis(4) as reduction and stabilizing agents. Additionally, the antimicrobial activity of these nanoparticles against both gram-positive (S. aureus, ATCC 25923) and gram-negative (E. coli, ATCC 25922; P. aeroginosa, PAO1), bacteria as well as fungus (C. albicans 90028) was evaluated. The nanoparticles (NPs) were characterised by various analyses, including TEM, SEM, XRD, FTIR, DSL, and zeta potential. Based on the TEM image, the ZnONPs exhibited a cluster of flower-like structures, whereas the Fe3O4NPs displayed a spherical shape with a varying size distribution. The zeta potential values for ZnO NPs ranged from -5.35 to -16.9, while for Fe3O4NPs ranged from -7.43 to -20.7. All ZnO nanoparticles exhibited antimicrobial activity exclusively against the S. aureus strain, whereas Fe3O4NPs did not demonstrate any antibacterial effect.

比较使用四种不同植物提取物合成的氧化锌和磁铁矿氧化铁纳米粒子的特性和抗菌活性

本研究的目的是采用沉淀法合成氧化锌（ZnO）和磁铁矿氧化铁（Fe3O4）纳米粒子，并以紫锥菊（Ocimum basilica）(1)、肉桂（Cinnamomum zeylanicum）(2)、沙门氏菌（Lactarius salmonicolor）(3) 和芍药（Paeonia kesrouanensis）(4) 的植物提取物作为还原剂和稳定剂。此外，还评估了这些纳米颗粒对革兰氏阳性（金黄色葡萄球菌，ATCC 25923）和革兰氏阴性（大肠杆菌，ATCC 25922；绿脓杆菌，PAO1）细菌以及真菌（白僵菌 90028）的抗菌活性。对纳米颗粒（NPs）进行了各种表征分析，包括 TEM、SEM、XRD、FTIR、DSL 和 zeta 电位。根据 TEM 图像，ZnONPs 呈现出一簇簇花状结构，而 Fe3O4NPs 则呈现出大小分布不一的球形。ZnO NPs 的 zeta 电位值在 -5.35 到 -16.9 之间，而 Fe3O4NPs 的 zeta 电位值在 -7.43 到 -20.7 之间。所有 ZnO 纳米粒子都显示出专门针对金黄色葡萄球菌菌株的抗菌活性，而 Fe3O4NPs 则没有显示出任何抗菌效果。
