Metal oxide nanoparticles have attained notable recognition due to their interesting physicochemical properties. Although these nanoparticles can be synthesized using a variety of approaches, the biological method involving plant extracts is preferred since it provides a simple, uncomplicated, ecologically friendly, efficient, rapid, and economical way for synthesis. In this study, the leaf extract was used as a reducing agent, and a green process was used to synthesize tin(ferrous: nickel)dioxide (Sn(Fe : Ni)O) nanoparticles. The synthesized nanoparticles were subjected to characterization by using X-ray diffraction (XRD), energy-dispersive X-ray (EDX) spectroscopy analysis, field emission scanning electron microscopy (FESEM), Fourier transform infrared (FTIR) spectroscopy, dynamic light scattering (DLS), and photoluminescence (PL) measurement. Furthermore, Sn(Fe : Ni)O nanoparticles were analyzed for their antimicrobial activity against Gram-positive and Gram-negative organisms including , and bacterial strains. XRD patterns revealed that Sn(Fe : Ni)O nanoparticles exhibited a tetragonal structure. The hydrodynamic diameter of the nanoparticles was 143 nm, as confirmed by the DLS spectrum. The FESEM image showed the spherical form of the synthesized nanoparticles. Chemical composites and mapping analyses were performed through the EDAX spectrum. The Sn-O-Sn and Sn-O stretching bands were 615 cm and 550 cm in the FTIR spectrum, respectively. Various surface defects of the synthesized Sn(Fe : Ni)O nanoparticles were identified by photoluminescence spectra. Compared to traditional antibiotics like amoxicillin, the inhibition zone revealed that Sn(Fe : Ni)O nanoparticles displayed remarkable antibacterial activity against all tested organisms, indicating the valuable potential of nanoparticles in the healthcare industry.
金属氧化物纳米颗粒因其有趣的物理化学性质而获得了显著认可。尽管这些纳米颗粒可以通过多种方法合成,但涉及植物提取物的生物方法是首选,因为它提供了一种简单、不复杂、生态友好、高效、快速且经济的合成方式。在本研究中,叶提取物被用作还原剂,并采用绿色工艺合成了二氧化锡(亚铁:镍)(Sn(Fe : Ni)O)纳米颗粒。通过使用X射线衍射(XRD)、能量色散X射线(EDX)光谱分析、场发射扫描电子显微镜(FESEM)、傅里叶变换红外(FTIR)光谱、动态光散射(DLS)和光致发光(PL)测量对合成的纳米颗粒进行了表征。此外,分析了Sn(Fe : Ni)O纳米颗粒对革兰氏阳性和革兰氏阴性生物体(包括 、 和 细菌菌株)的抗菌活性。XRD图谱显示Sn(Fe : Ni)O纳米颗粒呈现四方结构。如DLS光谱所证实,纳米颗粒 的流体动力学直径为143 nm。FESEM图像显示了合成纳米颗粒的球形形态。通过EDAX光谱进行了化学组成和映射分析。在FTIR光谱中,Sn - O - Sn和Sn - O伸缩带分别为615 cm和550 cm。通过光致发光光谱识别了合成的Sn(Fe : Ni)O纳米颗粒的各种表面缺陷。与阿莫西林等传统抗生素相比,抑菌圈表明Sn(Fe : Ni)O纳米颗粒对所有测试生物体均表现出显著的抗菌活性,表明纳米颗粒在医疗保健行业具有宝贵的潜力。
