Abstract

Stability of perfluorocarbon (PFC) emulsions with natural phospholipids as surfactants has been studied under conditions of long-term storage without freezing. Changes in the structure of emulsions were monitored with respect to the (i) general structure (characterized by the average diameter and particle size distribution) and (ii) microstructure (characterized by the index of interaction between PFC emulsion and the blood serum). It was shown that the particle size and structure of the studied emulsions were unchanged during 12-month storage at +4°C. The average particle diameter did not exceed 0.2 μm during the entire period of observations.
