Development of Li+ Selective Microelectrode Using PPy [3,3'-Co(1,2-C2B9H11)2] as a Solid Contact
Planar all solid-contact ion-selective microelectrodes (ASC-µISEs) with a conducting polymer (polypyrrole doped with cobaltabis(dicarbollide) anion [3,3'-Co(1,2-C2B9H11)2]) as a solid contact layer between the polymeric membrane sensitive to lithium (Li) and the gold (Au) substrate were prepare...
