Real–Time Acquisition and Visualisation of Ion Fluxes Using an Ion Camera Microchip [National Instruments Case Study]

Ion interactions in chemistry and biology are invisible to the human eye, so we can observe only the effects of the reactions, such as a liquid changing colour. With ion-sensitive field effect transistors (ISFETs), we can detect local fluctuating ionic concentrations—for example, pH—on the surface of the device. We can develop high-resolution images to show the motion of ions arranging ISFET sensors in an array architecture and reads the sensors in real time
