Small But Not Nano

A new concern about Nanotechnologies safety has been raised in a paper to be published by US and French Scientists. The concern is that the word ‘nanoparticle’ applies typically to anything that is smaller than 100nm. It is argued that this definition is not rigorous enough and that for health reasons the nanoparticles should have […]

Could Suncream be a Cause of Alzheimer’s Disease?

  A research group at the University of Ulster are investigating a possbile link between nanoparticels such as those found in suncream and Alzheimer’s disease. Professor Vyvyan Howard (toxicologist) and Dr Christian Holscher (expert in Alzheimer’s disease) have been awarded £350,000 to investigate any link that may present itself between nanoparticles and neurodegenerative disorders. There is […]

Response to Study Linking Nanoparticles to Pulmonary Fibrosis

  An aforementioned study to be realeased in the next issue of the ERJ has already warranted a response from certain members of the scientific community. The response highlights some of the reasons that could be attributed to the deaths seen as being caused by nanoparticles. There is no denial that some forms of nanoparticles […]

First Concrete Link Described Between Nanoparticles and Pulmonary Fibrosis

A study to be published in the next issue of the European Respiratory Journal (ERJ) has claimed the first concrete evidence that exposure to nanoparticles can cause disease. The discovery was made in workers who are exposed to nanoparticles during adhesive paint production, which have subsequently gone on to develop severe pulmonary fibrosis. Two of […]

Bacterial Nanomagnets for Medical Imaging

  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 […]

Oxidative Stress Induced by Iron Nanoparticles in Human Lung Cells

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 […]

Nanotechnology powers new X-ray scanner

  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 […]

The Problem of Nanotoxicology

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
