Procedures for manufacturing double-barrelled ion-sensitive microelectrodes employing liquid sensors.
Liquid ion-sensitive/selective sensors are available for most inorganic ions of physiological and biochemical importance. In order to measure intracellular ionic activities in relatively small cells, it is advisable to manufacture and use double-barrelled microelectrodes. Procedures for making two types of double-barrelled ion-sensitive microelectrode are described in detail. Such microelectrodes have been used successfully to measure intracellular K+, Cl- and Na+ activities in retinal horizontal cells of fish and body-wall muscles of insect larvae.
