摘要：
When bovine serum albumin (BSA) and dipalmitoylphosphatidylcholine (DPPC) compete for occupation of an air-water interface, the protein rapidly colonizes the interface, effectively hindering the access of the phospholipid, a situation encountered in certain pulmonary conditions. We found that DPPC can totally and irreversibly displace BSA from the surface of a gas bubble when submitted to sustained sinusoidal oscillations at frequencies in the range of those encountered in respiration, and this without recourse to any additive.
