    摘要: A biomolecule detector and a method thereof are provided to detect the biomolecules in a liquid sample using a field effect transistor (FET) array. The FET array is characterized in that the transistor used has no gate electrode layer, a reference electrode is provided in the space between the transistors in the array instead of the gate electrode layer. Using the FET array, the existence of the biomolecules in the sample can be detected electrically and effectively under the circumstance where an external voltage is applied to flow the biomolecules. Using the FET array to detect the biomolecules, the deviation for each transistor is reduced and the multiplex processing is also possible to measure the plurality of analyzing samples at the same time.

    摘要: A method for identifying a biomolecule using a biomolecule detector having a field effect transistor (FET) is provided. The method comprises the steps of (a) heating a sample containing a biomolecule loaded in the detector to thereby elevate the temperature of the sample; (b) measuring electric current flowing through a channel formed between a source region and a drain region in the FET while raising the temperature in the step (a); (c) obtaining a transition temperature that is the temperature at maximum point of current variation from data measured in the step (b); and (d) identifying the biomolecule using the transition temperature obtained in the step (c).
