The present study focused on the evaluation of antibacterial property of silver nanoparticles (AgNPs) synthesized using mango flower extract. The morphology of the synthesized AgNPs was observed under transmission electron microscopy and the particles have shown spherical shape in the range of 10-20 nm. X-ray powder diffraction analysis confirmed the crystalline nature of the AgNPs. The atomic percentage of the Ag element in the nanoparticles was about 7.58% which is greater than the other elements present in the sample. The AgNPs showed extensive lethal effect on both Gram-positive (Staphylococcus sp.) and Gram-negative (Klebsiella sp., Pantoea agglomerans, and Rahnella sp.) bacteria. The extensive lethal effect of AgNPs against clinically important pathogens demonstrated that the mango flower mediated AgNPs could be applied as potential antibacterial agent to control the bacterial population in the respective industries.
本研究旨在评估使用芒果花提取物合成的银纳米粒子（AgNPs）的抗菌性能。合成的 AgNPs 的形态通过透射电子显微镜进行观察，颗粒呈现出 10-20nm 范围内的球形。X 射线粉末衍射分析证实了 AgNPs 的结晶性质。纳米颗粒中 Ag 元素的原子百分比约为 7.58%，大于样品中存在的其他元素。AgNPs 对革兰氏阳性（葡萄球菌）和革兰氏阴性（克雷伯氏菌、成团泛菌和 Rahnella 菌）细菌均表现出广泛的致死作用。AgNPs 对临床重要病原体的广泛致死作用表明，芒果花介导的 AgNPs 可作为潜在的抗菌剂应用于各自行业控制细菌种群。
