Domains and anomalous adsorption isotherms of dipalmitoyl-phosphatidylcholine membranes and lipophilic ions: Pentachlorophenolate, tetraphenylborate, and dipicrylamine

Dipalmitoyl-phosphatidylcholine (DPPC) vesicles acquire negative surface charge on adsorption of negatively charged pentachlorophenolate, and lipophilic ions tetraphenylborate, and dipicrylamine. We have obtained zeta -potential isotherms from the measurements of electrophoretic mobility of DPPC ves...

Description
Summary:Dipalmitoyl-phosphatidylcholine (DPPC) vesicles acquire negative surface charge on adsorption of negatively charged pentachlorophenolate, and lipophilic ions tetraphenylborate, and dipicrylamine. We have obtained zeta -potential isotherms from the measurements of electrophoretic mobility of DPPC vesicles as a function of concentration of the adsorbing ions at different temperatures.
