Nanotubes present one of the most promising opportunities in nanotechnology with a plethora of applications in nanoelectronics, mechanical engineering, as well as in biomedical technology. Due to their structure and some physical properties, boron nitride (BN) nanotubes (BNNTs) possess several advantages over carbon nanotubes (CNTs), and they are now commercially produced and used on a large...

Cellular toxicity of TiO₂-based nanofilaments

Magrez, Arnaud ; Horvth, Lenke ; Smajda, Rita ; Salicio, Valérie ; Pasquier, Nathalie ; Forró, László ; Schwaller, Beat

In: ACS Nano, 2009, vol. 3, no. 8, p. 2274–2280

At present, nanofilaments are not exclusively based on carbon atoms but can be produced from many inorganic materials in the form of nanotubes and nanowires. It is essential to systematically assess the acute toxicity of these newly synthesized materials since it cannot be predicted from the known toxicity of the same material in another form. Here, the cellular toxicity of TiO₂-based...
