    摘要: A method of analyzing a nucleic acid fragment sample to judge whether the nucleic acid fragment sample is uncomplementary, partly complementary or complementary to a DNA fragment in its specific base sequence is conducted by the steps of: bringing an aqueous solution of the nucleic acid fragment sample into contact with a DNA chip having an electroconductive substrate and the DNA fragment fixed onto the substrate in the presence of an electrochemical thread intercalator; measuring an electric current flowing from or to the electroconductive substrate along the DNA fragment under application of a potential to the substrate; and comparing the electric current measured above with a referential electric current which is prepared employing a DNA chip equivalent to the above DNA chip, the intercalator, and an aqueous solution of a nucleic acid fragment which is complementary to the DNA fragment of the DNA chip.
