Conductive organic materials for DNA biosensors
Conductive organic materials have attracted great interest due to their excellent electronic and biochemical properties, which make them suitable for promising applications in chemical and biological sensing. With many advantages like labelfree and easy fabrication, DNA biosensors based on conductive organic materials have shown significant benefit for the rapid and highly sensitive genetic detection. Organic DNA sensors can be mainly divided into two types, which are based on electrochemical detection and organic thin-film transistors, respectively. This chapter gives a comprehensive description to these two types of DNA sensors, while the principles of sensors, relative organic materials, detection methods, transduction mechanisms, and their pros and cons are well addressed in detail. Moreover, some new developments and future perspectives in this field are also discussed.
