Web15 mrt. 2024 · For ion sensing, polymeric nanosensors commonly use an ionophore-based detection mechanism. This consists of an ion-binding molecule (“ionophore”) for analyte recognition coupled to a pH-responsive fluorescent molecule for signal transduction through maintaining a charge-balance in the organic phase. WebEssentially, the role of the ionophore is to promote a drastic change in the response pattern found in ionophore-free membranes exclusively containing the polymer, plasticizer, and ion exchanger. 16,17 Therefore, the ion-exchange process at the sample–membrane interphase relies on the extraction of the target ion from the solution ( i.e., … Web8 apr. 2024 · Based on the literature, IVR was determined potentiometrically using PVC membrane electrodes incorporating sulfonated calixarene and hydroxypropyl-ß-cyclodextrin (Abo-Talib et al., 2015) which exhibited low to moderate selectivity.
