Abstract:Carbon nanotube sensors were capable of detecting organophosphate insecticide binding to recombinant acetylcholinesterase (rAChE) immobilized on the sensor. The carbon nanotube sensors were fabricated by chemical vapor deposition method and it showed field effect transistor property. rAChE was immobilized by specific binding of NTA-Ni and His tag on the reverse side of the carbon nanotube sensor. The current between the source and drain was measured after incubation of various concentrations of organophosphate… Show more
“…Recombinant AChE was immobilized on the reverse side of the carbon nanotube sensor for detecting OP insecticides. 95 The current between the source and the drain was measured after incubation of various concentrations of OPs with immobilized AChE. Two OPs showed similar dose-response curves in measuring I ds -V gate correlation with the AChEimmobilized CNT sensors.…”
