Abstract
<h3>New oxygenation technique reduces damage to blood cells</h3> Procedures developed by a New Jersey scientist may lead to a new blood oxygenation technique that reduces the amount of blood hemolysis and protein denaturation. The approach, using a liquid membrane separation technique, utilizes oxygen bubbles coated with liquid films of solvent and a surfactant to permit oxygen transport into blood. Norman N. Li, PhD, of Esso Research and Engineering Corporate Research Laboratories, Linden, NJ, described his work at the recent American Chemical Society meeting in Washington, DC. A patent has been filed, and, the laboratory and the University of Pennsylvania School of Medicine, supported by the National Institutes of Health, are working on further applications of the technique. Dr. Li reported that stable, fluorocarbon-type liquid membranes that permit opposite transfer of oxygen and carbon dioxide can be formed around oxygen bubbles.
