Abstract
Disclosed is a biopolymer (DNA) detector capable of performing overall analysis including an unreacted sample without needing any complex work such as washing or the like. A DNA probe 66 is fixed to an electrode plate 22, and the electrode plate 22 is displaced by applying a DC voltage between electrode plates 22 and 23. Thus, sample DNA 63 to be detected can be separated. It becomes possible to obtain a clearer result by performing analysis based on a ratio of an entire reaction system.
Claims7
A biopolymer detector comprising:
- voltage supplying means for applying a voltage between two electrodes of a casing for housing biopolymers between the electrodes;
- electrode driving means for changing a distance between the electrodes;
- and
- measuring means for measuring an electrical characteristic between the electrodes or a change in the electrical characteristic while the distance between the electrodes is changing time-wise in a predetermined pattern.
