A group at the University of Tokyo have found a type of anerobic marine bacteria that produce magnetosomes, which are thought to help them navigate by following the earths magnetic field. These magnetosomes are formed by filling fatty vesicles with iron. This iron is then oxidised to form magnetite a highly magnetic form of iron. These [...]

In a study conducted by researchers at Berkeley and the University of California it has been indicated that zero-valent iron nanoparticles can cause oxidative stress to lung cells. This means that the introduction of these iron nanoparticles is correlated with an increase in reactive oxygen species (ROS) seen in the cells. The presence of ROS [...]

  At the University of North Carolina there has been a nanotechnology breakthrough in X-ray imaging. The breakthrough has come from carbon nanotubes being used to create a novel multi-beam source of X-rays. The carbon naotubes can be used as tiny electron guns, which dont have to heat up to create the X-rays. This means [...]

A large problem with Nanotoxicology is that a nanomaterials toxicology may be vastly different to its toxicology in another form i.e. as in nanoparticles. Understanding this nanotoxicology is key to creating harmless nanomaterials. To read more about nanotoxicology: Nanowerk
