Abstract：
:It is shown that activity in the area of chemically modified electrodes continues at a high level. This topic is increasing in popularity with a large research field on the incorporation of electroactive groups into a variety of conductive films. These developments are also directed towards catalyzing bioselective and biospecific reactions. Significant developments in the field of ion-selective electrodes have occurred and some exciting advances in all areas of these sensors are reported, albeit briefly.
