    摘要: Provided are an amperometric sensor and device for electrochemically quantifying nitrosothiol (RSNO), which is associated with storage and delivery of nitric oxide (NO) in the human body. The amperometric sensor for measuring a concentration of RSNO includes an electrode configured to measure an electric current generated by an oxidation reaction of NO, and a means configured to start and stop photo-induced decomposition of RSNO. Here, the electric current is measured by the oxidation reaction of NO before and after the photo-induced decomposition of RSNO. The amperometric sensor may measure separate signals of RSNO and NO, which are present in the sample at the same time, using one electrode, thereby preventing an inhibition action caused by NO during the measurement of RSNO. Also, the amperometric sensor is simple in structure and easy to manufacture and may be applied to manufacture of a small electrode, and thus may be developed as a sensor for in vivo measurements.

    摘要: There is provided a microchip-based differential-type carbon dioxide gas sensor for detecting dissolved carbon dioxide levels. It functions with at least one working electrode composed of an unbuffered hydrogel membrane containing a certain amount of sodium bicarbonate and a pH-sensitive gas-permeable membrane; and a reference electrode composed of a buffered hydrogel membrane and a pH-sensitive gas-permeable membrane. The unbuffered hydrogel membrane contains carbonic anhydrase, which reduces the time period for the hydration of carbon dioxide, thereby allowing the quick measurement of the level of carbon dioxide. In addition to being significantly improved in stabilization, sensing, and recovering time periods, the differential-type carbon dioxide gas sensor can be fabricated in small sizes and quickly measure levels of carbon dioxide dissolved in sample solution.

    摘要: Disclosed is a method for fabricating biosensors, using hydrophilic polyurethane. Bio-active reagents, including enzymes, antibodies, antigens, cells and receptors, are mixed with hydrophilic polyurethane and the mixture is directly coated over a signal transducer to form a sensing film which serves as a signal detector. The method using hydrophilic polyurethane allows the simplification of the fabrication of biosensors without conducting complicated chemical reactions and washing steps, such as crosslinking. The bio-active reagent entrapped within the hydrophilic polyurethane film can retains its high activity for an extended period of time and the intrinsic potentiometric response of the underlying ion-selective polymeric membrane is not affected by the bio-active reagent immobilized polyurethane film coated on its sensing surface. Therefore, the biosensors are superior in specificity, selectivity, and stability. Also, the adoption of solid-state type electrodes by virtue of the direct immobilization of the bio-active reagents allows the biosensors to be miniaturized, offering the advantages of the detection of small quantities of samples and mass production for low cost.
