A method for testing the impact of nanoparticles on the surface properties of monolayer of a pulmonary surfactant major component (DPPC) in a Langmuir-Wilhelmy balance system
Journal Title: Podstawy i Metody Oceny Środowiska Pracy - Year 2013, Vol 29, Issue 2
Abstract
This method is used to study the influence of particles of nanopowders on the surface properties of the main component of the pulmonary surfactant - dipalmitoylphosphatidylcholine (DPPC). The study consists in determining the changes in the surface pressure during the compression of DPPC monolayer formed on a surface of a suspension of the particles in saline. The assessment of the impact of nanoparticles on the surface properties of DPPC monolayer is carried out on the basis of the analysis of the compression isotherm of monolayer formed on the surface of a pure liquid phase and the compression isotherms of monolayer formed on the surface of the suspensions of various concentrations of nanoparticles.
