Major limitations found with nanotubes in blood facing medical devices
Dublin, Ireland (SPX) Jan 22, 2015
Scientists in the School of Pharmacy and Pharmaceutical Sciences in Trinity College Dublin, have made an important discovery about the safety issues of using carbon nanotubes as biomaterials which come into contact with blood. The significance of their findings is reflected in their paper being published as the feature story and front page cover of the international, peer-reviewed journal Nanomedicine. When blood comes into contact with foreign surfaces the blood's platelets are activated which in ... read more
