Abstract

Biosynthesized silver nanoparticles (Ag NPs) hold tremendous promise in nano-bioscience, with applications spanning engineering, science, and industry. This study delves into their fabrication process, crystallographic characteristics, and nanostructures. Employing green banana peel extract (GBPE), Ag NPs were synthesized. Various analytical techniques, such as UV-Vis absorption spectrophotometry (UV), X-ray diffraction (XRD), Gas chromatography-mass spectrometry (GC-MS), Field emission scanning electron microscopy (FESEM), Fourier-transform infrared spectroscopy (FTIR), and Transmission electron microscopy (TEM) elucidate their attributes. UV-visible analysis reveals a 413 nm absorption band due to surface plasmon resonance. The Ag NPs exhibit a face-centered cubic structure with an average crystallite size of 45.87 nm. Lattice parameters and dislocation density are also determined. When tested against harmful bacteria, such as and , advanced microscopy reveals a median size of particles of 55.12 nm and demonstrates their antibacterial characteristics. These environmentally benign Ag NPs also improve the efficiency of bio-electrochemical cells (BECs), opening the door to large-scale manufacturing at a reasonable cost and broadening the range of possible uses.

摘要

生物合成银纳米颗粒（Ag NPs）在纳米生物科学领域有着巨大的前景，其应用涵盖工程、科学和工业等领域。本研究深入探讨了它们的制备过程、晶体学特征和纳米结构。利用青香蕉皮提取物（GBPE）合成了Ag NPs。通过各种分析技术，如紫外可见吸收分光光度法（UV）、X射线衍射（XRD）、气相色谱-质谱联用（GC-MS）、场发射扫描电子显微镜（FESEM）、傅里叶变换红外光谱（FTIR）和透射电子显微镜（TEM）来阐明其特性。紫外可见分析显示，由于表面等离子体共振，出现了一个413 nm的吸收带。Ag NPs呈现面心立方结构，平均晶粒尺寸为45.87 nm。还测定了晶格参数和位错密度。当针对有害细菌（如 和 ）进行测试时，先进的显微镜显示颗粒的中位尺寸为55.12 nm，并证明了它们的抗菌特性。这些对环境无害的Ag NPs还提高了生物电化学电池（BECs）的效率，为以合理成本进行大规模制造打开了大门，并拓宽了可能的应用范围。
