DOI: 10.1039/b914268a
A novel kind of capsules-in-bead scaffold is developed to construct a spatially separated multienzyme cascade system. Each enzyme is first encapsulated in a guest microcapsule through synergy of biomimetic mineralization and layer-by-layer self-assembly; these microcapsules are then encapsulated into a millimeter-scale gel bead (host bead). This structured scaffold offers the possibility of individually manipulating the reactivity of each enzyme.
