摘要:
A QCM sensor including a sensor device, the sensor device having a crystal substrate, on both of front and rear surfaces of which a pair of electrodes are disposed so as to oppose with each other and the QCM sensor detecting and quantitatively analyzing components of a sample from either a variation in a fundamental resonant frequency or a variation in an impedance when a surface of one of the pair of electrodes is immersed into either a sample gas or a sample solution. The sensor device is arranged in a multi-channel structure such that four mutually opposing electrodes (11A through 14A, 12B through 14B) are disposed on both front and rear surfaces of the crystal substrate 10, each electrode being arranged to enable a fixation of a receptor which is different for each component of a sample to be detected and quantitatively analyzed, whereby the QCM sensor detects and quantitatively analyzes once the components of one sample different for different electrodes.

摘要:
The inventive photoreactive device has a semiconductor and an oxidation-reduction material. The semiconductor has a conduction band with a potential and being capable of producing electrons under the irradiation of light on the semiconductor. The oxidation-reduction material has a redox potential being positive compared with the potential of the conduction band. The semiconductor supplies electrons into the oxidation-reduction material to reduce it under the irradiation of light for storing the electrons. The stored electrons are discharged from the oxidation-reduction material into a metal material to prevent the corrosion of the metal material.
