Dissolution of zinc nanoparticles in pulmonary fluid

Inhaled from the ambient air nanoparticles may reach innermost areas of respiratory tract, alveolar sacs, particularly. In this work the dissolution of electroexplosive zinc nanoparticles (62 nm) in the synthetic alveolar has been studied. The evidence of the total solubility (99%) of metal nanopowders in the synthetic alveolar fluid had been demonstrated with the help of the stripping voltammetry. Alongside, the mechanism of zinc nanoparticles dissolution related to the electroexplosive zinc nanoparticles completely dissolving in the synthetic alveolar fluid has been proposed.
