REVIEW ARTICLES On the cytotoxicity of carbon nanotubes

carbon The two main variants single-walled carbon nano-tubes (SWCNTs) and multi-walled carbon nanotubes (MWCNTs) both possess a high tensile strength are ultra-light weight and have excellent chemical and thermal stability They also possess semi- and metallic-conductive properties The SWCNT is a one-atom thick sheet of

Understanding the hazards of nanomaterials

Carbon nanotubes (CNTs) are an example of a diverse group of HARN Some CNTs exist as long straight fibres and in the absence of evidence to the contrary it should be assumed that these types of CNTs have the properties identified in box 1 Other types of CNTs have a more tangled structure and exist as low density 'fluffy' bundles of nanotubes For these CNTs no

Nanotubes: A Carbon

A significant nanotechnology discovery that came to light in 1991 was carbon nanotubes Carbon nanotubes are cylindrical structures that have diameters as small as 1 nm and lengths up to several centimeters Carbon nanotubes have the highest strength-to-weight ratio of any known material Although carbon nanotubes are strong they are not brittle

Carbon nanotubes exposure risk assessment: From

6/17/2015Nanoscale size and fiber like structure of carbon nanotubes (CNTs) may determine high reactivity and penetration as well as the pathogenicity of asbestos and other mineral fibers Despite many in vitro and in vivo studies the absence of full-scale data on CNT effects on human health clearly point out the necessity for epidemiological studies Currently several projects are initiated
