Abstract

Electrosynthesized copolymers of pyrrole and N-methylpyrrole were characterized by in situ conductivity measurements at microarray electrodes and cyclic voltametry in aqueous solution. The redox properties were easily controlled by changing the monomer ratio in the polymerization solution. The microarray electrode coated with polypyrrole or the copolymer served as redox switching devices showing the rapid 'on' and 'off' responses (typically, within a few seconds) to redox reagents in solutions with high reproducibility. The copolymerization was effective to give selectivity and sensitivity to this device.
