使用香菇多糖绿色合成钯纳米颗粒，用于催化活性和生物应用
作者：
用于催化和生物应用的钯纳米颗粒(Pd NPs)的绿色合成引起了人们的极大兴趣。香菇多糖(LNT)可能是一种很好的还原稳定剂，可以替代复杂的植物提取物。在这项工作中，验证了一种使用LNT还原和稳定Pd纳米粒子的简单、绿色的方法。用紫外-可见光谱、差示扫描量热法、透射电子显微镜和X射线光电子能谱对LNT稳定的钯纳米粒子(PDN-LNT NPs)进行了表征。结果表明，PDN-LNT纳米粒子中的Pd纳米粒子尺寸较小(2.35~3.32 nm)。PDN-LNT纳米粒在溶液中稳定7d。此外，PdN-LNT纳米粒子对4-硝基苯酚的还原具有较高的催化活性。更重要的是，PDN-LNT纳米粒对细胞的毒性可以忽略不计，并显示出良好的抗氧化活性。综上所述，所制备的PDN-LNT纳米粒子在生物相关领域具有巨大的应用潜力。
The green synthesis of palladium nanoparticles (Pd NPs) for catalysis and biological applications has been gaining great interest. To replace complex plant extracts, lentinan (LNT) may be a good reducing and stabilizing agent. In this work, a simple and green method using LNT to reduce and stabilize palladium Pd NPs was verified. The resulting LNT stabilized palladium nanoparticles (Pdn-LNT NPs) were characterized by UV-Vis spectroscopy, DLS, TEM, and XPS. The results indicated that Pd NPs inside of Pdn-LNT NPs had a small size (2.35–3.32 nm). Pdn-LNT NPs were stable in solution for 7 days. In addition, Pdn-LNT NPs had higher catalytic activity towards the reduction of 4-nitrophenol than other catalysts. More importantly, Pdn-LNT NPs had negligible cytotoxicity towards cells and showed good antioxidant activity. Taken together, the prepared Pdn-LNT NPs have great potential bio-related applications.
