NANOPORE BASED ION-SELECTIVE ELECTRODES

摘要

Nanopore based ion-selective electrodes and methods of their manufacture as well as methods for their use are disclosed and described. The nanopore based ion-selective electrode can include a pore being present in a solid material (11 ) and having a nanosize opening (1) in the solid material (11), a metal conductor (9) disposed inside the pore opposite the opening (1) in the solid material (11), a reference electrode material (3) contacting said metal conductor (9) and disposed inside the pore, a conductive composition (5) in contact with the reference electrode (3) and disposed in the pore, and an ion-selective membrane (7). The ion-selective membrane (7) can be configured to isolate the metal conductor (9), reference electrode material (3), and conductive composition (5) together within the pore.
