Experimental assessments of metallic and metal oxide nanoparticles’ toxicity

IOP Conference Series: Materials Science and Engineering, 2019
Abstract Nanoparticles of metals and their oxides (Me-NPs) are of special interest in the light of health risks assessment and management, because, along with engineered Me-NPs, there exists usually a substantial fraction of nanoscale (“ultrafine”) particles of the same substances within the particle size distribution of condensation ...
