Abstract Inhaled pathogens, pollutants and therapeutics interact with the dynamic architecture of the alveoli, yet how individual particles move and deposit at cellular resolution remains unclear. Here, utilizing the crystal ribcage platform, we track aerosol transport in ex vivo, actively ventilated lungs using real-time fluorescence imaging with single-particle resolution, capturing droplet trajectories, free-flight motion, impact orientation and deposition timescales within functional alveoli.
Abstract The lung undergoes continuous remodeling throughout normal development and aging, including changes to alveolar and capillary structure and function. While histological methods allow static analysis of these age-related changes, characterizing the changes that occur in response to mechanical stimuli remains difficult, particularly over a dynamic, physiologically relevant range in a functioning lung.
