Research Focus

Dr. Possmayer developed a technique to purify and sterilize lung surfactant - a substance that allows lungs to expand and breathe.  After saving the lives of countless premature babies with BLES, the surfactant he developed, his work is now focused on adults.  BLES is manufactured in London and used by more than 99 percent of the neonatal intensive care units in Canada.
