Biosynthesis of silver nanoparticles (AgNPs) was achieved by a novel, simple green chemistry procedure using citrus sinensis peel extract as a reducing and a capping agent. The effect of temperature on the synthesis of silver nanoparticles was carried out at room temperature (25°C) and 60°C. The successful formation of silver nanoparticles has been confirmed by UV-vis, FTIR, XRD, EDAX, FESEM and TEM analysis and their antibacterial activity against Escherichia coli, Pseudomonas aeruginosa (gram-negative), and Staphylococcus aureus (gram-positive) has been studied. The results suggest that the synthesized AgNPs act as an effective antibacterial agent.
采用新型简单的绿色化学工艺，利用柑橘皮提取物作为还原剂和稳定剂，成功合成了银纳米粒子（AgNPs）。考察了温度（室温 25°C 和 60°C）对银纳米粒子合成的影响。通过紫外-可见吸收光谱、傅里叶变换红外光谱、X 射线衍射、能谱分析、场发射扫描电子显微镜和透射电子显微镜分析等手段，证实了银纳米粒子的成功形成，并研究了其对革兰氏阴性菌大肠杆菌和铜绿假单胞菌、革兰氏阳性菌金黄色葡萄球菌的抗菌活性。结果表明，所合成的 AgNPs 是一种有效的抗菌剂。
