Silver nanoparticles (AgNPs) have been biosynthesised through the extracts of fruits, which served as the reducing agents and capping agents. Biosynthesised AgNPs have been found to be ultraviolet-visible (UV-vis) absorption spectra since they have displayed one surface plasmon resonance peak at 438 nm, attesting the formation of spherical NPs. These particles have been characterised by UV-vis, field-emission scanning electron microscopy, energy-dispersive X-ray spectroscopy, X-ray diffraction, Fourier transform infrared spectroscopy, and transmission electron microscopy analysis. The formation of AgNPs at 1.0 mM concentration of AgNO has resulted in NPs that contained mean diameters in a range of 20-40 nm. The green-synthesised AgNPs have demonstrated high antibacterial effect against pathogenic bacteria (i.e. , , and ). Biosynthesising metal NPs through plant extracts can serve as the facile and eco-friendly alternative for chemical and/or physical methods that are utilised for large-scale nanometal fabrication in various medical and industrial applications.
银纳米颗粒（AgNPs）已通过水果提取物生物合成，这些水果提取物充当还原剂和封端剂。已发现生物合成的AgNPs具有紫外可见（UV-vis）吸收光谱，因为它们在438nm处显示出一个表面等离子体共振峰，证明了球形纳米颗粒的形成。这些颗粒已通过紫外可见光谱、场发射扫描电子显微镜、能量色散X射线光谱、X射线衍射、傅里叶变换红外光谱和透射电子显微镜分析进行了表征。在1.0mM浓度的硝酸银中形成AgNPs，得到的纳米颗粒平均直径在20-40nm范围内。绿色合成的AgNPs已证明对病原菌（即 、 和 ）具有高抗菌效果。通过植物提取物生物合成金属纳米颗粒可作为化学和/或物理方法的简便且环保的替代方法，这些方法用于各种医学和工业应用中的大规模纳米金属制造。
