摘要
Electronic detection of biomolecules is gradually emerging as effective alternative of optical detection methods. We describe transistor devices with carbon nanotube conducting channels that have been used for biosensing and detection. Both single channel field effect transistors and devices with network conducting channels have been fabricated and their electronic, characteristics examined. Device operation in (conducting) buffer and in a dry environment - after buffer removal - is also discussed.. The devices readily respond to changes in the environment, such effects have been examined using gas molecules and coating layers with specific properties. Finally the interaction between devices and biomolecules will be summarized. The application of devices for detecting biological processes and bio-electronic integration is described in the paper 5593-07.
