posted on 03/31/2011
Invention Summary: A method has been developed for constructing an ion selective electrode inside the pore volume of a glass nanopore electrode. The method consists of chemical or electrochemical depositing reference electrode materials, hydrogels, polymers and ion selective components sequentially to yield an ion selective sensor. The device exhibits exceptional stability in comparison to other miniaturized ion selective electrodes because the electrode materials are contained and protected within the pore. The device is simple to construct and has numerous applications in medical, pharmaceutical, homeland security, environmental, and military arenas.
Market Applications: The conical nanopore structure provides a very robust volume for containing the components of an ion selective electrode. Specifically, the reference electrode, internal filling solutions (including gels, hyrogels and polymers), and ion selective membrane are protected from the external solution, providing for an exceptionally stable and miniaturized ion selective electrode. At the same time, the pore shape provides a low resistance pathway between internal and external reference electrodes, critical for operation of the device. The small size of the device lends itself to development of a sensor array for simultaneous detection of multiple analytes. It has application in sensors for medical, pharmaceutical industry, homeland security, environmental, and military fields.
