Abstract

CNA) transferred electrons from the bulk water phase to Fe (CN) a3-in the internal water phase of the vesicles. The transmembrane electron transfer was found in all cases to proceed through diffusion of uncharged forms of the redox mediators (CMVO, CBO, and CNAO, respectively) but the kinetic behavior varied considerably. The mechanisms for CB and CNA were simple, the reaction following first-order kinetics, and the transmembrane ...
