The kinetics of ionic transfer across adsorbed phospholipid layers

Blocking effect of a phospholipid monolayer on ion transfer at a liquid | liquid interface and its electrochemical control

“…Cunnane et al [10] added 6.5 Â 10 À5 M ( ¼ mol dm À3 ) egg yolk lecithin to the DCE phase, and Chesniuk et al [11] injected a portion of 0.01 M dibehenoyl phosphatidylcholine solution near the interface to prepare the PC monolayer. In the latter case, the K þ transfer facilitated by a relatively small ionophore such as DB18C6 was not affected by the PC monolayer.…”

Ion transfer across the water|trifluorotoluene interface

“…Tetraphenylarsonium tetraphenylborate (TPAsTPB) was prepared as reported in Ref. [33]. Bis(triphenylphosphoranylidine)ammonium tetrakis(pentafluorophenyl)-borate (BATB) was prepared as reported in Ref.…”

Synergistic barrier effect of phosphatidylcholine and phosphatidic acid on the ion transfer across a polarized liquid–liquid interface and its electrochemical stability

“…Following the pioneering works on the blocking of ion transfer across the phospholipids membrane [15,16], the present authors demonstrated voltammetrically a large decrease of the ion permeability across the phospholipid monolayer adsorbed at a water-organic (W-O) solution interface, and its potential dependence [17]. It was concluded that the complex formation of phosphatidylcholine, PC, with lanthanide ions blocked the K + transfer facilitated by dibenzo-18-crown-6, DB18C6.…”
