Abstract

Due to increasing concerns about environmental impact and toxicity, developing green and sustainable methods for nanoparticle synthesis is attracting significant interest. This work reports the successful green synthesis of silver (Ag), silver-titanium dioxide (Ag@TiO), and silver-selenium dioxide (Ag@SeO) nanoparticles (NPs) using L. extract. Characterization by XRD, SEM, TEM, and EDX confirmed the successful formation of uniformly distributed spherical NPs with controlled size (25 ± 4.9 nm) and desired elemental composition. All synthesized NPs and the . extract exhibited potent free radical scavenging activity, indicating significant antioxidant potential. However, Ag@SeO displayed lower hemocompatibility compared to other NPs, while Ag@SeO and the extract demonstrated reduced inflammation in a carrageenan-induced paw edema animal model. Interestingly, Ag@TiO and Ag@SeO exhibited strong antifungal activity against and , as evidenced by TEM and FTIR analyses. Generally, the findings suggest that . -derived NPs possess diverse biological activities with potential applications in various fields such as medicine and agriculture. Ag@TiO and Ag@SeO, in particular, warrant further investigation for their potential as novel bioactive agents.

摘要

由于对环境影响和毒性的担忧日益增加，开发绿色可持续的纳米颗粒合成方法正引起广泛关注。这项工作报道了使用L.提取物成功地绿色合成了银（Ag）、银 - 二氧化钛（Ag@TiO）和银 - 二氧化硒（Ag@SeO）纳米颗粒（NPs）。通过XRD、SEM、TEM和EDX表征证实成功形成了尺寸可控（25 ± 4.9 nm）且元素组成符合要求的均匀分布的球形NPs。所有合成的NPs和提取物均表现出强大的自由基清除活性，表明具有显著的抗氧化潜力。然而，与其他NPs相比，Ag@SeO的血液相容性较低，而Ag@SeO和提取物在角叉菜胶诱导的爪肿胀动物模型中显示出炎症减轻。有趣的是，通过TEM和FTIR分析证明，Ag@TiO和Ag@SeO对 和 表现出强大的抗真菌活性。总体而言，研究结果表明，源自.的NPs具有多种生物活性，在医学和农业等各个领域具有潜在应用。特别是Ag@TiO和Ag@SeO，作为新型生物活性剂的潜力值得进一步研究。
