摘要

添加硝酸银(agno3)的小麦叶片水提物在100℃下培养2小时，观察到+0。430 nm处紫外可见光谱测定的表面等离子体共振证实了银纳米颗粒的形成。采用透射电子显微镜(TEM)对粒径为5 ~ 14nm的球形银纳米粒子进行了表征。采用圆盘扩散法和宏观稀释(管)肉汤法对大肠杆菌、金黄色葡萄球菌、克雷伯氏菌等具有潜在的抑菌活性。这种环境友好的方法为纳米颗粒的合成提供了一种简单、容易、快速和经济有效的方法，可用于医药和工业的多个领域。

COMPARATIVE ANALYSIS OF ANTIBACTERIAL ACTIVITY OF SILVER NANOPARTICLES SYNTHESIZED USING LEAF EXTRACT OF WHEAT VARIETIES

+0 was observed when an aqueous extract of wheat leaves augmented with silver nitrate (AgNO 3 ) was incubated for 2 hours at 100 o C. The formation of silver nanoparticles was con rmed by surface plasmon resonance as determined by UV-Vis spectra at 430 nm. Silver nanoparticles of size ranging from 5-14 nm of spherical shape were characterized using transmission electron microscopy (TEM). These nanoparticles were found to possess potential antibacterial activity against (Escherichia coli, Staphylococcus aureus, Klebsiella) using disc diffusion method and macro dilution (tube) broth method. This environmental friendly method provides a simple, easy, fast and cost effective method for nanoparticles synthesis and can be used in several areas of medicines and industries.
