中文摘要	a significant challenge in chemistry is to create synthetic structures that mimic the complexity and function of natural systems. here, a self-activated, enzyme-mimetic catalytic cascade has been realized by utilizing expanded mesoporous silica-encapsulated gold nanoparticles (emsn-aunps) as both glucose oxidase- and peroxidase-like artificial enzymes. specifically, emsn helps the formation of a high degree of very small and well-dispersed aunps, which exhibit an extraordinarily stability and dual enzyme-like activities. inspired by these unique and attractive properties, we further piece them together into a self-organized artificial cascade reaction, which is usually completed by the oxidase-peroxidase coupled enzyme system. our finding may pave the way to use matrix as the structural component for the design and development of biomimetic catalysts and to apply enzyme mimics for realizing higher functions.
