Abstract A ferrocene-containing multifunctional redox copolymer synthesized by radical polymerization for application of electrochemically active layer on an indium tin oxide (ITO) electrode. The surface adhesive monomer acts as an anchor to the ITO surface, the polyethylene glycol (PEG) group acts as an antibiofouling functionaliy, the epoxide group selectively conjugates antibodies on the polymeric ITO surface, and the ferrocene group is the redox-active compound for electron mediator. The ferrocene-containing polymer exclusively produced a distinguishing redox wave due to ferrocene, as opposed to the ferrocene-free polymer. To further demonstrate the usefulness of our polymer systems, we configured a sandwich immunoassay; the ferrocene-containing polymer largely improved the sensitivity and dynamic range of the immunoassay as compared to the ferrocene-free polymer.
