K Suzuki et al.
Analytical chemistry, 68(1), 208-215 (1996-01-01)
To develop an ionophore that is highly selective for sodium for use in an ion-selective electrode, we propose a model based on 16-crown-5 which has a cavity just the size of Na(+ )and has a "block" subunit to prevent complex
Judith A Heiny et al.
The Journal of general physiology, 151(9), 1146-1155 (2019-07-20)
Ion movements across biological membranes, driven by electrochemical gradients or active transport mechanisms, control essential cell functions. Membrane ion movements can manifest as electrogenic currents or electroneutral fluxes, and either process can alter the extracellular and/or intracellular concentration of the
