Аннотация:Spontaneous micelles formation by ionic surfactants has been detected amperometrically as an appearance of ion transfer across the water-dichloroethane interface noticed from linear dependence between the current and potential (Ohm's law). At low surfactant concentrations, when its spontaneous aggregation does not occur, the micelles formation facilitated by a potential across the interface has been registered. The transfer of redox inactive proteins through water-dichloroethane interface in the presence of surfactant has been observed voltammetrically. It has been shown, that the presence of protein does not affect thermodynamics of micelles formation, but accelerates kinetics of ion transfer through the interface. The electrochemically controlled transfer of redox inactive proteins through liquid\liquid interface may lead to the development of methods for direct amperometric detection of biomolecules.
