 note = {Electrochemical detection of the specific gene carrying aberrant methylated cytosine was achieved by ferrocenyl naphthalene diimide carrying β‐cyclodextrin (β‐CD), FNC, coupled with the probe‐DNA‐immobilized electrode. The five CpG sites in a 24‐base sequence were selected as the target DNA on the CDH4 gene, which is associated with colorectal cancer. When methylated and unmethylated samples hybridized with the DNA probe (HS‐M24) immobilized on the electrode, an increased current signal was observed in the electrolyte containing FNC and correlated with the amount of target DNA. Furthermore, an increase in current (115 %) was observed when the PCR product of 105 bp was hybridized on the HS‐M24‐immobilized electrode, whereas a background level of current increase was observed in the case of unmethylated product. Such large discrimination ability might be due to the inter‐ and/or intra‐complex formation of ferrocene with β‐CD of FNC on the surface of the electrode.},
