Au hydrogel with a well-defined nanowire network was rationally designed through one-step dopamine-induced self-assembly. Due to the porous nanostructure along with the polydopamine induced accumulation and interfacial electron transfer effects, the resulting Au hydrogel nanozyme exhibits enhanced glucose oxidase-like activity and peroxidase-like activity, with a biomimetic cascade catalysis.
通过多巴胺一步诱导自组装，合理设计了具有明确纳米线网络的水凝胶。由于多孔纳米结构以及聚多巴胺诱导的积累和界面电子转移效应，所得的 Au 水凝胶纳米酶表现出增强的葡萄糖氧化酶样活性和过氧化物酶样活性，具有仿生级联催化作用。
