In vivo Toxicity Studies of Pristine Carbon Nanotubes: A Review

Discovered in 1991(Iijima, 1991), carbon nanotubes (CNTs) have attracted considerable attention in many fields of science and technology because of their unique structural, mechanical, and electronic properties. Their potential seemed paramount in the fields of materials science, including conductive and high-strength composites, energy storage and energy conversion devices, sensors, field emission displays and radiation sources, hydrogen storage, nanometer-sized semiconductor devices, probes and interconnects (Dresselhaus et al., 2004). Thus their studies progressed rapidly during the last two decades.
