Ionophore-based
WebUnfortunately, ionophores were found to promote the loss of insufficiently lipophilic species from the ionophore-doped ISMs into aqueous samples. Here we report on an improved redox buffer platform based on equimolar amounts of the much less hydrophilic Co(III) and Co(II) complexes of 4,4â ²-dinonyl-2,2â ²-bipyridyl, which makes it possible to extend the … Web7 apr. 2024 · Here, we report a pH independent sensing principle based on nanospheres containing ionophores. As the ion-exchange occurs, the signal transducer undergoes aggregation-induced emission (AIE) or aggregation-caused quenching (ACQ), leading to a dramatic change in fluorescence intensity.

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. Yet, no MIP (ionophore) as ionophore has been reported for IVR determination. WebIonophore-based ISEs for bulky anions such as nitrate and perchlorate are essentially unknown, but ion-exchanger-based ISEs already possess good selectivity for these anions. Ionophores may operate on the basis of a range of recognition principles and are structurally quite diverse, 59 see Fig. 6.
