A new study suggests that exposure to titanium oxide nanoparticles causes rainbow trout to develop holes in their brains
In just the past few years, nanotechnology has brought technological advances in almost every field imaginable – patches that regenerate heart tissue, water-powered batteries and better biofuels are just a few examples. As with just about any new technology, however, concerns have been raised regarding its safety. We’ve never experienced anything quite like it before, so how far should we trust it? According to a recent study conducted at the University of Plymouth, the answer to that question might be “Not very far.” In tests on rainbow trout, titanium oxide nanoparticles were found to cause damage to the brain and other parts of the central nervous system.
