FET BASED SENSOR FOR DETECTING BIOMOLECULE, METHOD FOR PREPARING THE SAME, AND METHOD FOR DETECTING BIOMOLECULE USING THE FET BASED SENSOR

摘要

Provided is a SWNT-FET-based sensor for detection of biomolecules including an increased Schottky contact area, a method for preparing the same, and a method for detection of biomolecules using the SWNT-FET-based sensor . According to the method of the present invention, a SWNT-FET-based sensor for detection of biomolecules having a thin and increased Schottky contact area can be obtained. The biomolecule detection sensor exhibits a superior detection sensitivity, and can effectively detect both nonspecific adsorption of biomolecules and specific biomolecule-biomolecule interactions, even at a low concentration of 1 pM, for example.
