Ion-solvating membranes
WebThe ion channels are preferably purified polyhydroxybutyrate polyphosphate complexes extracted from organisms or prepared from the individual constituents which have been size selected. The bilayers are useful for testing the affect of various molecules and ions on the channel which correlates to the in vivo result. WebTherefore, chemical stability remains a significant challenge for anion conducting membranes. An alter- native is to use an ion-solvating membrane where an aqueous elec- trolyte is dissolved in a polymer matrix [10] so that it utilizes the uptake of an aqueous alkaline to achieve ionic conductivity and does no need for cation moieties [11 , 12 ].
