Ion-Selective Electrodes With Ionophore-Doped Sensing Membranes

At the time of this writing, more than 20 000 publications related to ion-selective electrodes (ISEs)1–7 have been published, with approximately two new ones per day in recent years. Figure 1 shows, for the period between 1970 and 2009, the continuing increase in the number of publications that could be readily recognized as reporting on the preparation or use of ionophore-based ISEs. Clearly, ...

Membranes: A Field-Theoretic Description

Blank membranes versus ionophore-based membranes for the selective determination of H+.

A pH electrode for the selective determination of H+ was introduced. Both phosphorated calix[6]arene and a N,N'-bisethoxycarbonyl-1,10-diaza-4,7,13,16-tetraoxacyclo-octadecane (DZCE) were used as new H+-ionophores. The calibration graphs of the obtained electrodes exhibits satisfactory Nernstian slopes. The electrodes were compared to blank membranes (without any ionophoric substances) for the ...

Fluidity of liposome membranes doped with metalloporphyrins: an ESR study.

Changes in membrane fluidity of porphyrin-doped liposomes have been investigated to assess the kinetics of the fluidization process. Metal complexes of tert-butylphenyl meso-substituted porphyrin, containing ions of Mg, Mn, Fe, Co, Ni and Cu, were used as dopants. Liposomes were obtained by sonication of hen egg yolk lecithin (EYL). Electron paramagnetic resonance (ESR) was applied using two sp...
