Title: Bio-sensor
Inventor: KAWAGURI MARIKO
IPC: G01N27/327
Filed: 1983-07-19
Abstract: PURPOSE:To attain to directly measure a minute amount of living body components in a specimen solution with high sensitivity without necessitating dilution or stirring, by forming a measuring electrode and an opposed electrode to an insulating substrate while providing a membrane, in which redox enzyme and coloring matter conjugated with said enzyme are contained, to a porous body so as to cover both electrodes. CONSTITUTION:A measuring electrode 7 and an opposed electrode 8, both of which are made of platinum, are respectively embedded in an insulating substrate 6 comprising polyvinyl chloride. The opposed electrode 8 is formed so as to have a suarface area two times or more of that of the electrode 7 in order to stabilize potential. In addition, for example, a nylon nonwoven fabric 9 is impregnated with a solution, which is prepared by adding and dissolving potassium ferricyanide being coloring matter in a solution prepared by dissolving redox enzyme 10 in a buffer solution (pH 5, 6), and the impregnated nonwoven fabric is dried to form a membrane so as to cover both electrodes. For example, when glucose oxidase is used as the enzyme 10, glucose in a specimen solution receives enzyme-coloring matter conjugated reaction and potassium ferricyanide is reduced. This reduced substance is oxidized to potassium ferrocyanide by applying voltage to the measuring electrode 7 and the generated current value is measured. By this method, the peak of the current value is compared with a preliminarily obtained calibration curve to measure a glucose concn. As a result, a concn. is determined without necessitating the weighing of a specimen.

Abstract: PROBLEM TO BE SOLVED: To form a colored film adapted to a design of an acrylic laminated injection molding and to secure excellent quality without problem, even by comparing with a conventional acrylic laminated injection molding by laminating a colored acrylic resin film having a total ray transmittance of a specific value or above on a surface. SOLUTION: The acrylic film laminated injection molding is formed by laminating a colored acrylic resin film having a total ray transmittance of a specific value or above on a surface. Then, if the transmittance of the film is less than 10%, a sense of transparency is insufficient and design properties are impaired. When a rear surface of the film (a decorating surface to become a connecting surface to the molding) is printed, a printed pattern becomes ambiguous. As the film, a film made of an acrylic resin in which rubber particles each having a particle size of 0.2 to 0.4 μm are dispersed and a pencil hardness of H or above is preferably used. Thus, excellent quality of no problem even by comparing with a conventional acrylic film laminated injection molding can be secured.
