In the present study, we have developed a green approach for the synthesis of silver nanoparticles (DSAgNPs) using aqueous extract of seed and determined its antibacterial, photocatalytic and cytotoxic effects. Surface plasmon resonance confirmed the formation of DSAgNPs with a maximum absorbance (λ) of 420 nm. SEM and TEM images revealed DSAgNPs were spherical and rod shaped, with a size range of 20 nm and 75 nm. The zeta potential was found to be -15.41 mV. XRD and EDX analyses confirmed the nature and presence of Ag and AgCl. DSAgNPs showed considerable antibacterial activity, exhibited better cytotoxicity against brine shrimp, and shown better photocatalytic activity against methylene blue. Based on the present research work, it can be concluded that DSAgNPs could be used in the field of water treatment, pharmaceuticals, biomedicine, biosensor and nanotechnology in near future.
在本研究中，我们开发了一种使用种子水提物合成银纳米粒子（DSAgNPs）的绿色方法，并测定了其抗菌、光催化和细胞毒性作用。表面等离子体共振证实了 DSAgNPs 的形成，其最大吸收（λ）为 420nm。SEM 和 TEM 图像显示 DSAgNPs 呈球形和棒状，尺寸范围为 20nm 和 75nm。Zeta 电位为-15.41mV。XRD 和 EDX 分析证实了 Ag 和 AgCl 的性质和存在。DSAgNPs 表现出相当的抗菌活性，对卤虫表现出更好的细胞毒性，对亚甲基蓝表现出更好的光催化活性。基于目前的研究工作，可以得出结论，DSAgNPs 可以在水处理、制药、生物医学、生物传感器和纳米技术等领域得到应用。
