在这项研究中，我们利用四种食肉植物的抗氧化潜力，以产生均匀和生物活性的银纳米粒子。聚乙烯吡咯烷酮的使用促进了准球形纳米粒子的合成，其特征在于稳定性和高均匀性。测试了它们对三种人类病原体和三种植物病原菌的活性。研究表明合成方法（微波辐射或热辐射）和植物提取物组成对纳米颗粒活性的影响。植物提取物的总抗氧化潜力以及银离子还原的应用方法被证明是抗微生物活性的关键。最高的最低杀菌浓度（平均值= 10 μ g/mL），获得了银纳米粒子的使用水提取物从Dionaea muscipula组织的合成。(C)2017年由Elsevier B. V.代表沙特国王大学制作和主持。
In this study, we exploit the anti-oxidative potential of four carnivorous plants to produce uniform and biologically active silver nanoparticles. The use of polyvinylpyrrolidone promoted synthesis of quasi-spherical nanoparticles characterized by stability and high uniformity. Their activity was tested against three human pathogens and three species of plant pathogenic bacteria. The study demonstrates the influence of synthesis method (microwave irradiation or heat radiation) and plant extract composition on nanoparticle activity. The total anti-oxidative potential of the plant extract, as well as the applied method of silver ions reduction proved to be crucial for antimicrobial activity. The highest minimal bactericidal concentration (mean value = 10 mu g/mL) was obtained for silver nanoparticles synthesized with the use of water extract from Dionaea muscipula tissue.
