METHOD FOR THE IMPROVING SENSITIVITY OF SENSORS ON THE BASIS OF A FIELD-EFFECT TRANSISTOR USING A SIGNAL AMPLIFICATION MARKER AND AN APTAMER SANDWICH COMBINATION, CAPABLE OF PROMOTING THE SAFETY OF HUMAN HEALTH AND ENVIRONMENT

摘要

PURPOSE: A method for the improving sensitivity of sensors on the basis of a field-effect transistor using a signal amplification marker and an aptamer sandwich combination are provided to sense non-polar substances.;CONSTITUTION: A method for the improving sensitivity of sensors senses non-polar substances which are hardly sensed by an existing carbon nanotube sensor. The method for the improving sensitivity of sensors additionally immobilizes substances with a charge to aptamers which combine with a sensing object and improves the sensitivity of the sensor by amplifying a sensor signal. The sensor signal is amplified and the sensitivity of the sensor is improved.;COPYRIGHT KIPO 2013;[Reference numerals] (AA) Signal amplification marker; (BB) Label aptamer; (CC) Non-polar substance; (DD) Probe aptamer; (EE) Substrate
