Nanotechnology is one of the key technologies of the 21st century and is associated with high expectations. Products with completely new properties for application in medicine, science, industry and various techniques are designed. However, the larger surface area of nanoparticles makes them highly reactive compared to larger sized particles of the same chemistry resulting in both, desirable and undesirable effects. The need for toxicological data has become increasingly important, thus several international projects are ongoing throughout the European Union. The question concerning the risks for the health and environment should not be disregarded.
