Abstract

We synthesized an α-helix forming polypeptide (CK30) and a random-coiled peptide (CdlK30) in order to clear the effect of secondary structure of the modifier on the electrochemical reaction in solution. By changing the surface structure of the CK30 from random-coil to α-helix, the electrochemical reaction of Fe(CN)₆⁴⁻ was suppressed. In contrast, on the CdlK30 modified electrode, the oxidation and reduction peak currents of the cyclic voltammogram increased.
