Phagocytizing cells recruitment and activity in response to pulmonary deposition of magnetite particles of different size in nanometer and micrometer ranges

, , , , , , , , , , ,
It is often maintained that nanoparticles are poorly recognized by host’s defence mechanisms and, specifically, cause weak attraction of phagocytes and are therefore removed from lungs ineffectively. However, intratracheal instillation of water-suspended magnetite nanoparticles caused [...]

Silicon Dioxide Nanoparticles Exert Dissimilar Cytotoxic Effects on Mammalian Cell Types

, , , , , , , , , ,
Applications of nanomaterials (e.g., silicon dioxide (SiO2) nanoparticles) are ubiquitous. Thus, environmental and occupational exposure to these nanoparticles could pose potential health risk. SiO2 microparticles are toxic in animals in vivo and SiO2 nanoparticles are [...]
