The range of themes addressed in this book emphasize key aspects and the future perspectives of nano-bioelectronics. The book discusses the electronic coupling of DNA and proteins with electronic devices to build new information systems and to apply the systems as biosensors. The exploitation of networks of neurons connected with electronic devices in future information processing systems and the use of nano-objects to assess cellular function is also discussed in detail. The topics of these hybrid nano-bioelectronic systems are both interesting for fundamental research and to enhance industrial competitiveness through research, education, and transfer of technology.
