Noncovalent entities (consisting of liposomes, phyto-nanosilver and carbon nanotubes) with interesting properties were constructed by a "green" bottom-up method. Phytosynthesis of silver nanoparticles using the Mentha piperita extract combines the benefits of this herb with the interesting properties of silver. The obtained silver-based biohybrids showed antioxidant and antimicrobial properties that have been considerable improved in the presence of carbon nanotubes. Thus the eco-designed bioconstructs consisting of cholesterol-containing liposomes, phytonanosilver and carbon nanotubes exhibited high antioxidant activity (AA=90.8%) and have been shown to be strong biocides offering inhibition zone of 25mm against Escherichia coli and 23mm against Staphylococcus aureus and Enterococcus faecalis.
通过“绿色”自下而上的方法构建了具有有趣特性的非共价实体（由脂质体、植物纳米银和碳纳米管组成）。使用薄荷提取物进行银纳米颗粒的植物合成，将这种草药的益处与银的有趣特性结合在一起。所获得的银基生物杂化物表现出抗氧化和抗菌特性，在碳纳米管存在的情况下，这些特性有了显著改善。因此，由含胆固醇脂质体、植物纳米银和碳纳米管组成的生态设计生物结构体表现出高抗氧化活性（AA = 90.8%），并且已被证明是强大的杀菌剂，对大肠杆菌的抑菌圈为25毫米，对金黄色葡萄球菌和粪肠球菌的抑菌圈为23毫米。
