Abstract

A sensing apparatus comprising an ion sensitive field effect transistor arranged to generate an electrical output signal in response to localized fluctuations of ionic charge at or adjacent the surface of the transistor, and means for detecting the electrical output signal from the ion sensitive field effect transistor, the localized fluctuations of ionic charge indicating events occurring during a chemical reaction.
