An electrochemical biosensor for the enzymatic sensing of glucose was constructed from poly(ferrocenylsilane) (PFS) polycations and glucose oxidase (GOx). PFS polycations and the negatively charged GOx were deposited layer�by�layer on an electrode surface, making use of electrostatic interactions between these components. In the resulting layer�by�layer structures, the PFS chains served as redox mediator and GOx as biorecognition element. Multilayer fabrication, including the exploration of crosslinking methods to enhance the stability of these multilayers, and sensing characteristics of the layers will be discussed.
