This chapter is intended to serve as a mini-tutorial rather than a comprehensive review. Discussions focus upon fundamental aspects of electrochemically mediated electron transfer. Examples are provided to illustrate the major concepts and a sample procedure is provided.
The effects of a crowded environment on DNA-mediated electron transfer were evaluated using a pyrene-modified oligonucleotide containing a hole-trapping nucleobase in poly(ethylene glycol) mixed solutions. Rapid decompositions of hole-trapping bases...
