The purpose is to make possible the label-free, stable, continuous, and easy detection of a reaction between a reagent and a filament-shaped biomolecule or polymer bridging between a pair of electrodes. To this end, there is provided a molecule detection system for detecting a reaction with a reagent within a liquid 37 of a molecule captured between electrodes, the system being equipped with: a detection device that is provided with a pair of electrodes, and with which it is possible to measure the resonance frequency and amplitude of the electrodes; a microfluid device 30 that is provided with a microfluid flow passage 36 including on a side surface thereof an opening part 36c in which is formed a gas-liquid boundary surface through which the electrodes can pass; a pressure-control microfluid pump 33 connected to an outlet 36b of the microfluid flow passage; a movable holding platform for holding the detection device or the microfluid device 30 in a movable manner; and a control device for controlling the detective device, pressure-control microfluid pump 33, and movable holding platform. |
