Method of detecting biochemical substances and sensor for use in said method.

摘要

A method of detecting biochemical substances which method comprises chemically binding and immobilizing a probe DNA having a sequence complementary with a sequence specific to a DNA of a biochemical substance onto an electrode of a frequency conversion element, hybridizing the probe DNA with a sample to detect said DNA as a target DNA having a sequence specific to the probe DNA, and measuring frequency changes corresponding to mass changes due to hybridization to detect and identify a hybridized DNA; and a sensor use in the above method.
