Abstract

The main component governing selectivity in ion-selective electrodes and optodes is the ionophore. For this reason, a member of natural products that possess selective ion-binding properties have long been sought after. By applying this principle, the performance of cyclosporin used as neutral carriers for calcium selective polymeric membrane electrode was investigated. The calcium ion-selective electrode based on cyclosporin gave a good Nernstian response of 26.6 mV per decade for calcium ion in the activity range <TEX>$1{\times}10^{-6}M$</TEX> to <TEX>$1{\times}10^{-2}M$</TEX>. The optimized calcium ion-selective electrode displayed very comparable selectivity for <TEX>$Ca^{2+}$</TEX> ion against alkali and alkaline earth metal ions, <TEX>$Na^{2+}$</TEX>, and <TEX>$Mg^{2+}$</TEX> in particular.
