摘要： In the manufacture of a substrate with a hydrophobic film used for a reference electrode of an ion sensor or the like, a hydrophobic film is formed on a substrate by irradiating a target consisting of a hydrophobic compound with a neutral atom beam and thereby effecting sputtering. The apparatus for effecting the sputtering comprises a target base disposed in a vacuum chamber, an atom beam gun for irradiating a target on the target base with a neutral beam, a substrate base and a shutter for controlling the passage of sputtered particles. A thin film that is manufactured is suitable for an ion sensor, such as an ISFET or the like or an enzyme sensor.

摘要： A film-coated sensor is formed by providing an electrically conductive substrate (2), which has a sectional area of less than 10.sup.-5 cm.sup.2, connected to a lead wire (5) at one end of an insulative capillary (1) and inscribed in the capillary (1), and providing a coating film (7) at another end, which is open, of the capillary (1) by an electrolytic polymerization process.The film-coated sensor obtained has a surface which is uniform, the film coating is easy to control, and since the sensor is not readily susceptible to flow of a specimen fluid, there is little drift and response is quick. Owing to its small size, the sensor is capable of measuring very small samples and of performing measurement upon being directly inserted into a living body or tissue.The sensor can be used also as an enzyme sensor by coating the surface of the film-coated sensor with a fixing enzyme film.

摘要： A biological information measurement apparatus is adapted to measure biological information in an extracorporeal circuration or in a living body by various measurement circuits comprising circuit elements which are not affected by electrical disturbances, and to transmit the results of measurement in the form of a non-electrical signal which is not affected by electrical disturbances. Measured values from measurement sections are gathered at a central processing section separated from the measurement sections. The processing section converts the measured values into output values, compensates the values for temperature and outputs the values to a display unit and recorder.

摘要： PCT Filed Nov. 19, 1987 PCT Pub. No. WO88/04050 PCT Pub. Date Jun. 2, 1988.An insulative substrate (1) is coated with an electrically conductive layer (2) and a redox layer (3) which comprises an electrolytic polymerization film of 2,6-dimethylphenol, and the surface of the redox layer is provided with an enzyme-fixed (7). The enzyme electrode thus obtained exhibits a potentiometric response, and the enzyme-fixed layer has a strong adhesion. As a result, sensitivity is high, there is little drift and service life is prolonged. An ion-selective field-effect transistor can be used instead of the insulative substrate (1).

摘要： An ion sensor includes an electrically conductive substrate, a redox layer coating the surface of the electrically conductive substrate, a barrier layer coating the surface of the redox layer, and an ion-selective layer coating the surface of the barrier layer. The barrier layer functions to prevent migration between the ion-selective layer and redox layer of substances constituting these layers, and to transmit a potential difference produced in the ion-selective layer by contact with an ion from the ion-selective layer to the redox layer.
