Ion-selective polymer dots for photoelectrochemical detection of potassium ions

Potassium-selective polymer dots (K-Pdots) containing potassium ionophores were for the first time used for photoelectrochemical (PEC) analysis and yielded sensitive and specific detection of potassium ions. The successful PEC analysis using ion-selective Pdots underscored the effectiveness of the strategy deployed and suggested the potential universality of this strategy for the detection of metal ions, which should advance the development of PEC sensors in ion analysis.
