Text of Abstract
In this work, we explore how to best mimic the behavior of lung surfactants in the alveolar environment. To this end, we compare interfacial structures formed via spreading and adsorption, and assess interfacial rheology under dynamic conditions that mimic breathing. We study native, exogenous, and model surfactant systems, and identify exogenous replacements as effective physiological analogues. Thin film balance, shear, and dilatational rheology experiments are performed to characterize the most representative systems.
