Deviation in pulmonary surfactant structure-function activity can impair airway patency and lead to respiratory 8 disorders. This novel study aims to evaluate the influence cigarette / e-cigarette vapour has on model 9 surfactant films located within a simulated pulmonary environment using a lung biosimulator. 10Chromatographic analysis confirmed that nicotine levels were consistent with the sampling regimen
