Abstract
A monolithic sensor chip containing a sensor array of 400 individually addressable platinum microelectrodes has been fabricated. This sensor array can be used in potentiometric mode as well as in amperometric m ode for redundant measurements with signal averaging, multi-analyte me asurements and imaging of analyte distributions. The sensor array is c oated with an ammonium-selective PVC membrane for creating a chemical sensor array and, additionally, with a urease membrane for creating a biosensor array. Thus, two-dimensional imaging of the distributions of ammonium and urea can be obtained.
