Schematic Drawing of the Sensor Device Using the Aptamer-Modified CNT-TFT

Caption

Clinicians most often monitor antibodies because these small proteins attach to antigens, or foreign substances, we face every day. Most biomolecules, however, have complicated charge characteristics, and the sensor response from conventional carbon nanotube systems can be erratic. A team in Japan recently revealed how these systems work and proposed changes to dramatically improve biomolecule detection. They report their findings in the Journal of Applied Physics. This image shows a schematic drawing of the sensor device using the aptamer-modified CNT-TFT.
