Abstract:
A polynucleotide detecting device comprising:a polynucleotide probe chip comprising a substrate having a concave portion; gels immobilized in holes which are formed in a flat surface of the concave portion, penetrate the substrate and have tapered side faces; and different polynucleotide probes immobilized in the gels;an electrode vessel in which a first electrode is located, and in which is a lower surface of the polynucleotide probe chip;a second electrode which is set in a solution including sample polynucleotides added onto a surface of the polynucleotide probe chip; anda switch which changes, plural times, polarities of the first and second electrodes, to migrate the sample polynucleotides in the gels of the respective holes by electrophoresis, thereby hybridizing the polynucleotide probes immobilized in the gels with the sample polynucleotides.
