ELECTRODE, SENSOR, FLUID DEVICE, AND MANUFACTURING METHOD OF ELECTRODE

PROBLEM TO BE SOLVED: To provide an electrode capable of reducing fluctuation of electric potential.SOLUTION: An electrode comprises: a first member having silver as a main component; a second member which has silver chloride as a main component and is in contact with at least a part of the first member; and a self-organized monomolecular film formed on the surface of the second member. The electrode may contain alkane thiol derivative in which the self-organized monomolecular film is chemically adsorbed on the surface of the second member. Further, a sensor comprises: a reference electrode having the first member having silver as a main component, the second member which has silver chloride as a main component and is in contact with at least a part of the first member, and the self-organized monomolecular film formed on the surface of the second member; and a working electrode including a detection part which detects biomolecules contained in solution being an object to be measured.SELECTED DRAWING: Figure 1 【課題】電位の変動を低減可能な電極を提供する。【解決手段】銀を主成分とする第１の部材と、塩化銀を主成分とし前記第１の部材の少なくとも一部と接する第２の部材と、前記第２の部材の表面に形成された自己組織化単分子膜と、を備えた電極。前記電極は、前記自己組織化単分子膜が、前記第２の部材の表面に化学吸着したアルカンチオール誘導体を含んでもよい。また、銀を主成分とする第１の部材と、塩化銀を主成分とし前記第１の部材の少なくとも一部と接する第２の部材と、前記第２の部材の表面に形成された自己組織化単分子膜と、を有する参照電極と、測定対象となる溶液中に含まれる生体分子を検出する検出部を備える作用電極と、を備えるセンサー。【選択図】図１
