Beschreibung
Zusammenfassung:	Porous golden interiors: Highly organized macroporous metal structures can be synthesized by the preparation of ordered colloidal crystals by the Langmuir–Blodgett technique and subsequent precision electrodeposition controlled by current oscillations. After the assembly of a bioelectrocatalytic chain in the pores, these tailored surfaces can be used as transducers with currents increased by more than one order of magnitude (see diagram).
