We herein present a simple, fast, efficient and environmentally friendly method for preparing silver nanoparticles (AgNPs) using the solution plasma method in the presence of extracts from (). The effects of extract concentrations and the applied voltage on the formation of AgNPs were investigated. Surface plasmon resonance spectra show a strong peak at 413 nm for the prepared samples. The Fourier-transform infrared spectroscopy measurement results indicated the presence of possible functional groups in the prepared AgNPs. Morphological analysis revealed that the AgNPs were spherical with an average size of 8 nm. The prepared AgNPs exhibited good stability in solution compared to that of AgNPs prepared by the solution plasma technique without extract. The formation mechanism of AgNPs is also proposed. The prepared AgNPs exhibited high antibacterial ability against Gram (+) , Gram (-) bacteria and strong anticancer activity for the AGS gastric cancer cell line. The obtained results demonstrated that this is a simple, rapid, environmentally friendly method for preparing AgNPs instead of conventional methods using chemical reducing agents for potential applications.
我们在此介绍一种简单、快速、高效且环保的方法，即在（）提取物存在的情况下，使用溶液等离子体法制备银纳米颗粒（AgNPs）。研究了提取物浓度和施加电压对AgNPs形成的影响。表面等离子体共振光谱显示，制备的样品在413nm处有一个强峰。傅里叶变换红外光谱测量结果表明，制备的AgNPs中存在可能的官能团。形态分析表明，AgNPs呈球形，平均尺寸为8nm。与未使用提取物通过溶液等离子体技术制备的AgNPs相比，制备的AgNPs在溶液中表现出良好的稳定性。还提出了AgNPs的形成机制。制备的AgNPs对革兰氏阳性菌、革兰氏阴性菌表现出高抗菌能力，对AGS胃癌细胞系具有强抗癌活性。所得结果表明，这是一种简单、快速、环保的制备AgNPs的方法，可替代使用化学还原剂的传统方法用于潜在应用。
