[0094] [Electrodes used to manufacture enzyme-immobilized electrodes]
[0095] figure 1 A shows the electrode 10 for manufacturing an enzyme-immobilized electrode according to the first embodiment.
[0096] Such as figure 1 As shown in A, an electrode 10 for manufacturing an enzyme-immobilized electrode comprises a mixture comprising carbon particles and a water-insoluble hydrophilic binder. The mixture usually contains at least carbon particles and a water-insoluble hydrophilic binder as main components, and preferably consists of carbon particles and a water-insoluble hydrophilic binder. For example, the ratio of the mass of the water-insoluble hydrophilic binder to the mass of the carbon particles in the mixture is 0.01 or more and 1 or less.
[0097] For example, the carbon particles are carbon black (ketjen black, ...
Embodiment 1
[0107] Electrode 10 for manufacturing an enzyme-immobilized electrode was formed using Ketjen black as carbon particles and ethyl cellulose as a water-insoluble hydrophilic binder in the following manner.
[0108] 1 g of Ketjen Black and 0.4 g of ethylcellulose were mixed, 7.5 g of terpineol was added to the mixture, and the mixture was stirred twice for 10 minutes each to prepare paste 12.
[0109] Such as image 3 As shown in A, a nonwoven fabric 14 is used as the substrate 11 . Such as image 3 As shown in B, the paste 12 was coated on a non-woven fabric 14 with a thickness of 50 μm by a coating machine, and heated on a hot plate at 75° C. for 2 hours to dry and remove terpineol.
[0110] In this way, the electrode 10 for manufacturing an enzyme-immobilized electrode comprising Ketjen black and ethyl cellulose was formed on the nonwoven fabric 14 . At this time, the formed electrode 10 for manufacturing an enzyme-immobilized electrode is partially buried in the nonwoven ...
