摘要

金属氧化物纳米颗粒因其独特的物理化学性质而受到广泛的关注。虽然这些纳米颗粒的合成方法多种多样,但植物提取物的生物合成方法是首选的,因为它提供了一种简单、不复杂、生态友好、高效、快速和经济的合成方法。本研究以印楝叶提取物为还原剂,采用绿色工艺合成二氧化锡(亚铁:镍)纳米粒子(Sn(Fe: Ni)O2)。通过x射线衍射(XRD)、能量色散x射线(EDX)光谱分析、场发射扫描电镜(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,还分析了Sn(Fe: Ni)O2纳米颗粒对革兰氏阳性和革兰氏阴性菌(包括金黄色葡萄球菌、肺炎链球菌、枯草芽孢杆菌、肺炎克雷伯菌、大肠杆菌和铜绿假单胞菌)的抗菌活性。XRD分析表明,Sn(Fe: Ni)O2纳米颗粒呈四边形结构。DLS谱证实纳米颗粒的水动力直径为143 nm。FESEM图像显示合成的纳米颗粒呈球形。通过EDAX光谱进行化学合成和图谱分析。在FTIR光谱中Sn-O- sn和Sn-O的拉伸带分别为615 cm-1和550 cm-1。利用光致发光光谱对合成的Sn(Fe: Ni)O2纳米颗粒表面的各种缺陷进行了表征。与传统抗生素如阿莫西林相比,抑制区显示,Sn(Fe: Ni)O2纳米颗粒对所有被试生物都具有显著的抗菌活性,表明纳米颗粒在医疗保健行业的宝贵潜力。

Assessment of Structural, Optical, and Antibacterial Properties of Green Sn(Fe : Ni)O2 Nanoparticles Synthesized Using Azadirachta indica Leaf Extract.

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 Azadirachta indica leaf extract was used as a reducing agent, and a green process was used to synthesize tin(ferrous: nickel)dioxide (Sn(Fe : Ni)O2) 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)O2 nanoparticles were analyzed for their antimicrobial activity against Gram-positive and Gram-negative organisms including Staphylococcus aureus, Streptococcus pneumoniae, Bacillus subtilis, Klebsiella pneumoniae, Escherichia coli, and Pseudomonas aeruginosa bacterial strains. XRD patterns revealed that Sn(Fe : Ni)O2 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-1 and 550 cm-1 in the FTIR spectrum, respectively. Various surface defects of the synthesized Sn(Fe : Ni)O2 nanoparticles were identified by photoluminescence spectra. Compared to traditional antibiotics like amoxicillin, the inhibition zone revealed that Sn(Fe : Ni)O2 nanoparticles displayed remarkable antibacterial activity against all tested organisms, indicating the valuable potential of nanoparticles in the healthcare industry.
