Abstract
An object is to stably, continuously and easily detect reactions of filamentary biomolecules or polymers bridging between a pair of electrodes against reagents without employing any marker or labeling substances. A molecule detecting system for detecting a reaction of a molecule captured between electrodes to a reagent in a liquid 37, the system comprising: a detection device including a couple of electrodes and being capable of measuring a resonance frequency and an amplitude of the electrodes; a microfluidic device 30 including a microfluidic channel 36 which includes a channel opening 36c on its one side, wherein an air-liquid interface the electrodes can pass through is formed in the channel opening 36c; a pressure controlled microfluidic pump 33 connected to an outlet 36b of the microfluidic channel 36; a movable holding device movably holding the detection device or the microfluidic device 30; and a controller controlling the detection device, the pressure controlled microfluidic pump 33, and the movable holding device.
