Abstract
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).
