Zinc oxide is recognized as one of the best antimicrobial agents. Zinc oxide nanoparticles were fabricated through a green approach using zinc sulfate, zinc nitrate, and zinc acetate dihydrate as precursors and an extract of Justicia adhatoda leaves as a reducing agent. The synthesized zinc oxide nanoparticles were checked for their antimicrobial activity against the bacterial strains Staphylococcus aureus, Escherichia coli, Pseudomonas aeruginosa, and the fungal strains Aspergillus niger, Aspergillus flavus, and Aspergillus fumigates. All three zinc oxide nanoparticles were found to inhibit the growth of microbes by the release of zinc ions and production of reactive oxygen species followed by destruction of microbes. Antimicrobial results of zinc oxide nanoparticles from the three different precursors were compared.

Justicia adhatoda叶片绿色合成氧化锌纳米粒子及其抑菌活性

氧化锌被认为是最好的抗菌剂之一。通过绿色方法使用硫酸锌,硝酸锌和二水合乙酸锌作为前驱体,并用Justicia adhatoda叶提取物作为还原剂来制备氧化锌纳米颗粒。检查合成的氧化锌纳米颗粒对金黄色葡萄球菌,大肠杆菌,铜绿假单胞菌黑曲霉,黄曲霉熏蒸霉菌菌株的抗菌活性。。发现所有三个氧化锌纳米颗粒均通过释放锌离子和产生活性氧物种,随后破坏微生物来抑制微生物的生长。比较了来自三种不同前体的氧化锌纳米颗粒的抗菌效果。
