Crystallized silver nanoparticles (AgNPs) were synthesized by using the eco-friendly Artocarpus heterophyllus biomaterial. The synthesis of AgNPs was a green approach and a rapid method. The AgNPs were characterized by field-emission scanning electron microscopy (FE-SEM), Fourier transform infrared spectroscopy, X-ray diffraction and inductively coupled plasma atomic emission spectroscopy. The FE-SEM analysis showed that the size of the synthesized AgNPs ranged around 45 nm. The plant leaves acted as both a reducing and a capping agent. The synthesized AgNPs showed an absorption peak at 400–440 nm. The biosynthesized AgNPs were tested for their antimicrobial activity against both the gram-positive bacterium Staphylococcus aureus and the gram-negative bacterium Escherichia coli and the fungus Aspergillus niger. The method used in the present work is simple, rapid, single-step, environment-friendly and very cheap and is an alternative to the current physicochemical methods. The antimicrobial activity of biosynthesized AgNPs suggests their possible application in the medical and pharmaceutical industry.

AH叶提取物合成银纳米粒子及其抗菌活性

结晶化的银纳米颗粒(的AgNPs)通过使用环境友好的合成波罗蜜生物材料。AgNPs的合成是一种绿色方法,也是一种快速方法。通过场发射扫描电子显微镜(FE-SEM),傅立叶变换红外光谱,X射线衍射和电感耦合等离子体原子发射光谱对AgNPs进行表征。FE-SEM分析表明,合成的AgNPs的大小约为45 nm。植物叶片既充当还原剂又充当封盖剂。合成的AgNPs在400–440 nm处显示吸收峰。测试了生物合成的AgNP对革兰氏阳性细菌金黄色葡萄球菌和革兰氏阴性细菌的抗菌活性大肠杆菌和真菌黑曲霉。本工作中使用的方法简单,快速,一步法,环境友好且非常便宜,并且是当前物理化学方法的替代方法。生物合成的AgNPs的抗菌活性表明它们可能在医学和制药行业中应用。
