A Novel Solid-State PVC-Membrane Potentiometric Dopamine-Selective Sensor Based on Molecular Imprinted Polymer

A novel solid-state polyvinylchloride (PVC) membrane potentiometric dopamine-selective microsensor was constructed based upon dopamine-imprinted polymer used as the ionophore in the membrane structure. The optimum membrane composition was determined as 4% (w/w) MIP, 69% (w/w) bis(2-ethylhexyl) sebac...

Zusammenfassung:	A novel solid-state polyvinylchloride (PVC) membrane potentiometric dopamine-selective microsensor was constructed based upon dopamine-imprinted polymer used as the ionophore in the membrane structure. The optimum membrane composition was determined as 4% (w/w) MIP, 69% (w/w) bis(2-ethylhexyl) sebacate (DOS), 26% (w/w) PVC, and 1% (w/w) potassiumtetrakis(4-chlorophenyl) borate (KTpClPB). The detection limit of the microsensor was determined to be 3.71×10-7 mol.L-1. The microsensor exhibited a super-Nernstian response for dopamine over the concentration range of 10-6-10-1 mol.L-1, with a short response time (
