Dread is an awful counselor. In the comic book series “Asterix,” the Gaul chief Vitalstatistix might be worried about the possibility that the sky may fall on his head. In reality, be that as it may, dangers ought to be evaluated with a clear mind. To guarantee that hazard appraisals are not done sincerely yet prompt appropriate decisions, researchers use models to examine the risk potential of substances or technologies. Empa analysts are at present researching the dangers of a moderately new class of substances produced using modest materials: drugs made utilizing nanomaterials. It is as of now realized that conventional pharmaceuticals can be released into the environment after being administered or ingested. In the animal world, for instance, hormone-like substances can prompt thin-shelled bird eggs, fertility issues in fish and populace decrease in otters.

Nanomedicine, on the opposite side, is as of now announcing promising results with new medications. With nano-diamonds, doctors are defeating the blood-brain barrier, and with gold nanoparticles, they are battling cancer. No errand appears to be too huge for the tiny particles. Little is thought about the dangers of this kind of nanomaterial when they are released into the environment.

Empa analysts led by Bernd Nowack from the “Technology & Society” lab in St. Gallen are at present calculating the dangers of these nanomedicines. Among different activities, the group is engaged with the international research and innovation project “BIORIMA.” The interdisciplinary project builds up the hazard the management of nanobiomaterials for people and the environment and is supported by “Horizon2020,” EU’s research and innovation funding program.
