The synthesis of a novel microemulsion system composed of a mixed fluorinated and hydrogenated oil C 8 F 17 CH 2 CH CH C 4 H 9 with a biocompatible hydrogenated surfactant, Montanox 80 is described. Investigation of the solubility of oxygen in these microemulsions showed that they absorbed more oxygen than Fluosol-DA which is currently used as an oxygen transporter in biomedical applications. Oxygen absorption was similar to that of blood. Light scattering ...
