| Research Abstract |
Electrochemical DNA detection has been studying in light of health-care biochip and other related fields. It is also important to detect double stranded DNA amplified by PCR under homogeneous solution to check influenza type or norovirus. This can be achieved our developed detection system of double stranded DNA in homogenous solution. Ferrocenylnaphthalene diimide carrying beta-cyclodextrin (FNC) provides signal-on type electrochemical detection of double stranded DNA without DNA-immobilized electrode. FNC shows intramolecular inclusion complex between ferrocene and beta-cyclodextrin with diminished current signal. After bound to double stranded DNA, the complex is collapsed resulting in recovered current signal with positive shift of redox potential. One can detect PCR product electrochemically with high sensitivity under homogenous solution.
