New technology for the detection of pH.
The measurement of pH is the most widely employed test for (bio-)chemical lab. Since the first use of glass electrode to detect pH, new techniques and methods have broaden the scope of pH detection. Metal/metal oxide, ion sensitive field-effect transistors (ISFET), fibre-optical techniques, nanotechniques, and conducting polymer techniques have been extensively developed. This review covers the various methods for pH detection. New development trends were discussed.
