Ion-selective electrodes, often abbreviated as ISEs, are electrochemical sensors that measure the activity of specific ions in a solution. They work by creating a potential difference across a selectively permeable membrane that interacts with the target ion. This potential difference is then measured against a stable reference electrode, and the resulting voltage is proportional to the logarithm of the ion's activity, following the Nernst equation.
The key component of an ISE is its sensing membrane, which is designed to be permeable to
The development of ISEs has revolutionized analytical chemistry by offering a simple, rapid, and often portable
