A sandwich-like antibacterial reagent (Ag/HNTs/rGO) was constructed through the direct growth of silver nanoparticles on the surface graphene-based HNTs nanosheets. Herein, various nanomaterials were combined by adhesion effect of DOPA after self-polymerization. Ag/HNTs/rGO possess enhanced antibacterial ability against E. coli and S. aureus compared with individual silver nanoparticles, rGO nanosheets or their nanocomposites.
通过在基于石墨烯的碳纳米管（HNTs）纳米片表面直接生长银纳米颗粒，构建了一种三明治状抗菌试剂（Ag/HNTs/rGO）。在此，通过多巴胺（DOPA）自聚合后的粘附作用将各种纳米材料结合在一起。与单独的银纳米颗粒、rGO纳米片或它们的纳米复合材料相比，Ag/HNTs/rGO对大肠杆菌和金黄色葡萄球菌具有更强的抗菌能力。
