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 [...]
A new method to enhance drug delivery has been developed at UC Santa Barbara. The method utilizes a biological system of gaining access to cells.
One of the most difficult barriers to cross in drug delivery is the movement of the drug from the circulation into the tissue. This technique provides a ay of achieving this.
A [...]
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 now evidence that [...]
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 are toxic [...]
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 [...]
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 [...]
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.
