Nanoparticle News and Research RSS Feed - Nanoparticle News and Research

In nanotechnology, a particle is defined as a small object that behaves as a whole unit in terms of its transport and properties. It is further classified according to size: in terms of diameter, fine particles cover a range between 100 and 2500 nanometers, while ultrafine particles, on the other hand, are sized between 1 and 100 nanometers.
Nanoparticle exposure can trigger dormant viruses in lung tissue cells

Nanoparticle exposure can trigger dormant viruses in lung tissue cells

Nanoparticles from combustion engines can activate viruses that are dormant in lung tissue cells. This is the result of a study by researchers of Helmholtz Zentrum München, a partner in the German Center for Lung Research, which has now been published in the journal 'Particle and Fibre Toxicology'.
