Cyclic voltammograms recorded in 10 mM K3[Fe(CN)6] in 0.1 M KCl. The potential was swept in the range between −250 and 700 mV (vs Ag/AgCl) with a sweep rate of 100 mV s−1: (a) bare gold electrode (red); (b) gold electrode modified with polytyramine layer (black); (c) the same as (b) after immobilization of 25-mer oligo-C (green); (d) as in (c) after treatment with 1-dodecanethiol (blue).(For interpretation of the references to colour in this figure legend, the reader is referred to the web version of this article.)
