Abstract

Presently, there is considerable emphasis on biological synthesis of nanoparticles containing bioactive reducing compounds with an aim to mitigate the harmful effects of pollutants. The approach under study is simple and ideal for the production of durable antimicrobial nanomaterials by novel single-step green synthesis of TiO metal oxide nanostructures using ginger and garlic crude aqueous extracts with bactericidal and catalytic activity. A variety of experimental techniques were used to characterize the synthesized nanomaterials. As demonstrated using x-ray diffraction and ultra-violet visible spectroscopy, the produced nanoparticles exhibited high absorption at 318 nm with size varying between 23.38 nm for ginger and 58.64 nm for garlic in biologically-reduced TiO. At increasing concentrations (500, 1000 µg/50 µl), nanoparticles reduced with garlic exhibited enhanced bactericidal efficacy against multiple drug-resistant S. aureus and effectively decomposed toxic methylene blue (MB) dye. In conclusion, biologically-reduced TiO nanoparticles may prove an effective tool in the fight against microbial illnesses and drug resistance.

摘要

目前,人们非常重视含有生物活性还原化合物的纳米粒子的生物合成,旨在减轻污染物的有害影响。本研究方法简单,理想,可通过使用具有杀菌和催化活性的姜和大蒜粗水提取物,在新型一步绿色合成 TiO 金属氧化物纳米结构中,生产出耐用的抗菌纳米材料。采用多种实验技术对合成的纳米材料进行了表征。结果表明,所制备的纳米粒子在 318nm 处表现出高吸收,在生物还原的 TiO 中,尺寸在姜的 23.38nm 和大蒜的 58.64nm 之间变化。随着浓度(500、1000μg/50μl)的增加,用大蒜还原的纳米粒子对多重耐药性金黄色葡萄球菌表现出增强的杀菌功效,并有效分解了有毒的亚甲基蓝(MB)染料。总之,生物还原的 TiO 纳米粒子可能成为对抗微生物疾病和耐药性的有效工具。
