Abstract

This disclosure relates generally to potassium ion sensors and monomers derived from such sensors. The disclosure also provides for polymers (e.g., random copolymers, nanoparticles, polymer thin films, and sensors) having polymerized monomeric potassium ion sensors as described herein. These compounds and polymers are useful for measuring intracellular and extracellular potassium ion concentrations.
