Plasticizer-free and pH-independent ion-selective optode films based on a solvatochromic dye

Author affiliations

Abstract

A layer of a solvatochromic dye, an ionophore, and an ion-exchanger deposited on a Nylon membrane enables highly selective colorimetric and fluorometric ion sensing. This new platform does not suffer from interference from the sample pH and does not require a plasticizer to dissolve the sensing chemicals.
