Surfactometry
WebINTRODUCTION A pulmonary surfactant (PS) is a lipid-protein complex that covers the entire air-water surface of the lung as a thin film (1,2). It consists of 80% phospholipids, … 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.
