Physiological tests reveal effects of hydrophobic surfactant proteins on interfacial rheology and surface stress.

The research aims to investigate pulmonary surfactant dynamics and the effects of hydrophobic surfactant proteins on interfacial properties.
Applied physiological-like compression/expansion cycles to PS-mimicking interfaces
Utilized dilatational rheology and neutron reflectometry
Analyzed different concentrations of SP-B and SP-C proteins
Identified conditions for multilayer formation affecting interfacial rheological properties
Measured changes in composition and interface thickness at physiological temperatures

Collada et al. (2026) studied this question.
