Strontium stannate nanorods (SrSnO NRs) were synthesized in the present study via a green, sustainable, and cheap method with leaf extract from Juniperus communis L. UV-visible spectroscopy (UV-Vis), Fourier-transform infrared spectroscopy (FTIR), X-ray diffraction (XRD), and Field emission scanning electron microscopy (FESEM) with energy-dispersive X-ray analysis (EDAX) were performed to investigate the SrSnO NRs. The particle size distribution (PSD) of SrSnO NRs characterized by using dynamic light scattering (DLS) analysis. The UV-visible spectra of the synthesized SrSnO NRs showed an absorption peak at 279 nm. SEM images confirmed that SrSnO NRs, which have an average size of about 29 nm, include a bunch of rod-like structure. In addition, the as-formed SrSnO NRs demonstrated excellent antibacterial activity against the bacteria Staphylococcus aureus, Enterococcus faecalis, and Escherichia coli. The synthesized SrSnO nanorods also exhibited a significant amount of antioxidant activity. It is also an attractive biocompatible choice for pharmacological and medical applications.
在本研究中,采用绿色、可持续且廉价的方法,以杜松叶提取物合成了锡酸锶纳米棒(SrSnO NRs)。利用紫外可见光谱(UV-Vis)、傅里叶变换红外光谱(FTIR)、X射线衍射(XRD)以及带有能量色散X射线分析(EDAX)的场发射扫描电子显微镜(FESEM)对SrSnO NRs进行了研究。通过动态光散射(DLS)分析对SrSnO NRs的粒度分布(PSD)进行了表征。合成的SrSnO NRs的紫外可见光谱在279 nm处显示出一个吸收峰。扫描电子显微镜图像证实,平均尺寸约为29 nm的SrSnO NRs包含一束棒状结构。此外,新形成的SrSnO NRs对金黄色葡萄球菌、粪肠球菌和大肠杆菌表现出优异的抗菌活性。合成的SrSnO纳米棒还表现出显著的抗氧化活性。它也是药理学和医学应用中一个有吸引力的生物相容性选择。
