ABSTRACT:
Disclosed is an ion sensor with its electrode covered with a water-repelling organic chemically adsorbed film, which is formed with at least one hole permitting the passage of ions and preventing the passage of biopolymers, thereby accurately measuring ion concentrations over a long period. In forming a silane-based chemically adsorbed monomolecular film on the surface of the electrode, a hole dozens of angstroms in diameter is formed on an organic thin film by physically adsorbing the mask compound and then washing it away. This ion sensor can prevent the passage of macromolecules such as proteins in a living body. The sensor can also be used in a solution containing numerous impurities, and can be applied for monitoring activities in the body by implanting it in a body.
