We have fabricated local-electrolyte-gated carbon nanotube field-effect transistors (CNTFETs); in which the electrolyte functions as a local top gate. The local-electrolyte-gated CNTFETs in the electrolyte solution provided high performance in terms of subthreshold slope and transconductance; resulting from the modulation of the conduction in the carbon nanotube channel and the large gate capacitance. Using the local-electrolyte-gated CNTFETs; real-time protein detection based on the channel conductance modulation was successfully demonstrated. Our local-electrolyte-gated CNTFETs are promising candidates for the development of nanoscale electronic and molecular-sensing device applications. © 2008 The Japan Society of Applied Physics;
