Wormlike iron oxide nanostructures were synthesized via a simple hydrothermal route for antibacterial application. The synthesized samples were characterized using different techniques for determining the morphology, elemental composition, crystal structure, magnetization, and optical properties. Field-emission scanning electron microscope images confirmed the formation of wormlike nanostructures. The mean diameter of wormlike particles was estimated to be around 30 nm. The x-ray diffraction pattern of the synthesized sample showed the formation of α-Fe₂O₃ or hematite with a rhombohedral lattice system and Raman spectroscopy confirmed this result. The bandgap of the material was estimated to be about 1.72 eV using ultraviolet–visible spectroscopy. The antibacterial activity of nanopowder was investigated on two bacteria, Escherichia coli and Staphylococcus aureus. Each bacteria strain was cultured in its specific culture medium containing two concentrations (1% and 2%) of iron oxide nanopowder. The nanoparticles were first irradiated by two UV lamps at zero (control), 30 min, 60 min, and 120 min. Sampling and culturing were performed for all times, the UV lamps were then turned off, and sampling and culturing were repeated after 24 h. Each microorganism was cultured in the appropriate conditions, and after 24 h, the number of bacteria was counted. The results of this experiment for both bacteria showed that irradiation with UV rays as well as different concentrations of iron oxide nanoparticles reduced the number of bacteria and the concentration of 2% caused a further decrease in the number of bacteria. The best result was obtained by simultaneous application of the 2% nanoparticle concentration and UV irradiation.

蠕虫状氧化铁纳米结构是通过简单的水热途径合成的，用于抗菌应用。使用不同的技术对合成的样品进行表征，以测定其形态，元素组成，晶体结构，磁化强度和光学性质。场发射扫描电子显微镜图像证实了蠕虫状纳米结构的形成。蠕虫状颗粒的平均直径估计为约30 nm。合成的样品的x射线衍射图显示形成的α-Fe ₂ ö ₃或带有菱形六面体晶格系统的赤铁矿和拉曼光谱仪证实了这一结果。使用紫外可见光谱法估计该材料的带隙约为1.72 eV。研究了纳米粉对两种细菌，即大肠杆菌和金黄色葡萄球菌的抗菌活性。。将每种细菌菌株在其包含两种浓度（1％和2％）的氧化铁纳米粉的特定培养基中进行培养。首先在零（对照），30分钟，60分钟和120分钟下用两个UV灯照射纳米颗粒。一直进行取样和培养，然后关闭UV灯，并在24小时后重复取样和培养。在适当的条件下培养每种微生物，并在24小时后对细菌数进行计数。该实验对两种细菌的​​结果均表明，紫外线照射以及不同浓度的氧化铁纳米粒子减少了细菌的数量，而2％的浓度导致细菌数量的进一步减少。
