摘要：

Get wired! The layer-by-layer electrostatic self-assembly of a redox enzyme as glucose oxidase (GOx) and a redox polymer mediator allowed different spatial organizations of both components to be explored. These organized systems (see picture) can work efficiently in molecular recognition, redox mediation, and generation of an electrical signal. Moreover, differences in GOx electrical wiring efficiency have been detected with the different assembling strategies.
