WebAug 18, 2024 · Pulmonary surfactant, also known as lung surfactant, is a detergent-like, lipid-protein mixture synthesized by alveolar type II epithelial cells. Adsorption leads to a thin film at the air-water surface of the lung. The major biophysical function of this lung surfactant film is to reduce the alveolar surface tension to near-zero value. ... WebFirst, we have developed a novel animal-free model called constrained drop surfactometry (CDS), which mimics the intra-alveolar environment and nano-bio interactions in the lungs (see Image 1). We have shown that CDS can accurately predict the extent of the acute lung injury and toxicity of various inhaled nanoparticles.
WebApr 10, 2024 · Pulmonary surfactant is a lipid-protein complex that forms a thin film at the air-water surface of the lungs. This surfactant film defines the elastic recoil and respiratory mechanics of the lungs. One generally accepted rationale of using oxygenated perfluorocarbon (PFC) as a respiratory medium in liquid ventilation is to take advantage of …
