Cells contain isolated compartments that spatially confine different enzymes, enabling high-efficiency enzymatic cascade reactions. Herein, the authors report a cell-inspired design of biomimetic cascade catalysis system by immobilizing Fe single atoms and Au nanoparticles on the inner and outer layers of three-dimensional nanocapsules, respectively, to enable highly selective colorimetric glucose detection.
