Abstract: Electrochemical labeling of double-stranded (ds) DNA
is achieved by redox-active DNA intercalators. Threading intercalators
derived from naphthalenediimide appended with ferrocene reporter group
in the side arms are particularly useful for this purpose. This allows
a sensitive electrochemical detection of DNA hybridization on an array,
providing a great potential for low-cost, high-throughput, and quick
DNA screening technique in post-genome study.
