Environment monitoring, security and food quality control Nanotechnological solutions for water and food biotoxins

The presence of biotoxins in food and water is a general threat to human health that causes many diseases and even mortalities worldwide every year.

In the last years nanotechnology has been commonly applied to this problem, mainly devoted to the development of new detection systems for monitoring. However, nanotechnology could also help to a better comprehension of the pharmacokinetic and bio-distribution of toxins in the human body when they are consumed. Furthermore, new nano-based applications can be used to detoxify water, mollusks or blood.

Our main aim is to explore the possible applications of nanotechnology in the field of both seawater and freshwater toxins and the future perspectives that this emerging approach can contribute with to the monitoring, risk management and toxicological knowledge about biotoxins.
