Our inhaled air contains a multitude of molecules, dust particles and biological components (pollen, bacteria, viruses, plant fibres etc.). In addition to gas molecules such as oxygen, which is very important to us, other unwanted things also enter our respiratory tract. The olfactory mucosa is an important barrier here.What role does the olfactory mucosa play in the possible absorption of nanoparticles via nasal breathing? Where is this olfactory mucosa located at all? Is there a direct connection to the brain? What do research studies say? Answers to these and other questions...

The JRC just released a report clarifying the key concepts and terms used in the European Commission's nanomaterial definition. This will support stakeholders for the correct implementation of legislation making reference to the definition.Nanotechnology may well be one of the most fast-moving sectors of the last few years.The number of products produced by nanotechnology or containing nanomaterials entering the market is increasing.As the technology develops, nanomaterials are delivering benefits to many sectors, including: healthcare (in targeted drug delivery, regenerative...

New DaNa Article Feb 2019
The application of metallic nanoparticles is being widely investigated for various nanomedicines. Especially in novel diagnostic and therapeutic tools they have a high potential. How can ironoxide carbohydrate nanoparticles help against iron deficiency? What kind of Nanomedicin with iron is available and what kind of effects have been observed?The recently published DaNa-article "Ironoxide carbohydrate nanoparticles for iron deficiency" will answer these and other questions and can be found in our Cross-Cutting section. Access the full article via the following link...

Graphene Review ACS Nano 2019
End of January 2019, members of the Graphene flagship published a review on safety assessment of graphene-based materials in the journal ACS Nano. The publication gives a comprehensive overview of all aspects of graphene health and environmental impact, focussing on the potential interactions of graphene-based materials with key target organs including immune system, skin, lungs, cardiovascular system, gastrointestinal system, central nervous system, reproductive system, as well as a wide range of other organisms including bacteria, algae, plants, invertebrates, and vertebrates in various...
