We present new preliminary data from arrays of ion sensor field effect transistors (ISFETs). Two devices are presented. The first consists of a planar array of ISFETs that are operated as an ion image sensor enabling the direct observation of ion flow over the surface of the chip in real-time. The second is an innovative form of Coulter-counter that is fully implemented in a CMOS-MEMS format. The device is tested as a cytometer by observing the flow of red-blood cells.
