    摘要: Provided is a field effect transistor (FET) type biosensor including a source electrode, a gate, and a drain electrode. A ligand that can bind to a side of a nucleic acid is added to the surface of the gate. In a conventional FET type biosensor, it is difficult to detect a signal within the debye length because a target nucleic acid is directly fixed to the surface of a gate of the conventional FET. However, in the present invention, this problem can be overcome and the debye length can be increased by treating the surface of a gate of an FET sensor with a ligand that can bind to a side of a nucleic acid. The ligand can be adsorbed onto the surface of the gate. In this case, the nucleic acid is adsorbed parallel to the surface of the gate, not perpendicular to the surface of the gate, thus generating an effective depletion region. In addition, hybridization efficiency can be increased because a hybridized sample can be injected into an FET sensor at high ionic strength.

    摘要: Disclosed herein is a method of positively detecting toxic materials within a sample, the method including contacting sub-mitochondrial particles with an electron donor. The electron donor is reacted with an electron transfer system of the sub-mitochondrial particles to produce a reactant. A pH indicator has its pH adjusted to be in a range of 9 to 11. The pH indicator is added to each reactant. Color changes in the pH indicator permit the detection of toxins present in the sample.

    摘要: A method of increasing discrimination for a target DNA having a polymorphic site is provided. The method includes: synthesizing a first probe by artificially substituting a base of a probe which is fully complementary to a target DNA having a polymorphic site by a mismatched natural base and synthesizing a second probe by artificially substituting a base of another probe having a single base mismatch at a position corresponding to the polymorphic site of the target DNA with a mismatched natural base; synthesizing a first hurdle DNA which is fully complementary to the first probe and is shorter than the first probe and a second hurdle DNA which is fully complementary to the second probe and is shorter than the second probe; immobilizing the first and second probes on a substrate; hybridizing the immobilized first and second probes with the first and second hurdle DNAs, respectively; and hybridizing the target DNA with the hybrids. The addition of a hurdle DNA and variation of a probe base can improve an ability of discriminating a single base mismatch.
