HYBRIDIZATION SENSING PART, SENSOR CHIP, AND HYBRIDIZATION METHOD

摘要

A hybridization sensing part (1a) for improvement of hybridization efficiency by a contrivance of aligning and immobilizing a sensing nucleotide chain in an elongated state. The reaction region (R) to serve as a field of hybridization of a sensing nucleotide chain (X) and a target nucleotide chain (Y) having a base sequence complementary to the sensing nucleotide chain (X) can be immobilized at the end (E) of a scanning electrode (C) by dielectrophoresis while elongating the sensing nucleotide chain (X) by an electric field. A sensor chip having such a sensing part (1a) and a hybridization method using them are also disclosed.
