In August, we would like to present a paper of the German BMBF project nanoGRAVUR. nanoGRAVUR dealt from 2015-2018 with the grouping of nanostructured materials with regard to occupational safety, consumer and environmental protection and risk mitigation. The approach is now described by the project partners in this paper.
Due to the variety of synthetic nanomaterials and the numerous modifications (differences in size, shape, chemical composition and surface functionalization), the effort required to investigate effects and behaviour within the framework of regulatory requirements is enormous. Given the variability of possible effects, it is almost impossible to examine the potential risk for each nanomaterial on a case-by-case basis. Grouping or analogy now aims to allow a reliable prediction of hazards from nanomaterials of a group without additional testing by identifying certain properties or parameters.
For each of the three different areas of occupational, consumer and environmental safety, different groups may emerge, but they are based on a harmonised set of material properties with specific analytical methods, descriptors and areas. Proof of concept is provided in this publication by quantitative data on 34 case studies.

Spotlight February 2021: Nanoobjects in the COVID-vaccine – scientifically correct?
The COVID-19 pandemic induces very different reactions of people on the internet (https://www.cdc.gov/mmwr/volumes/70/wr/mm7002e1.htm) and in the social networks. Without following the conspiracy theories as “5G nanochip hidden in COVID vaccines” some news as “COVID vaccines induce allergic reactions” should be scientifically recognised. The picture from the 5G-nanochip whose plan goes viral on the internet is […]Read more
Spotlight March 2021: Is Nanotechnology the Swiss Army Knife against Future Pandemics?
The COVID 19 outbreak has led to a fundamental rethinking of existing approaches to diagnosis, treatment, and prevention methods. The need for better and more efficient concepts is global and urgent. Nanotechnology has long been at the forefront of innovation and has led to advances in many different disciplines. Could this interdisciplinary field help develop […]Read more
Spotlight September 2020: Groundwater remediation with Carbo-Iron® – Risk or Benefit?
In September we would like to present a paper of the BMBF project Fe-Nanosit. The project dealt with the use of iron-containing nanomaterials in groundwater and wastewater remediation. A comprehensive assessment and weighing of benefits and possible environmental risks resulting from the application is now presented by the project partners in this paper. Groundwater is indispensable for the […]Read more
Spotlight November 2020: Nanotechnology in the public perception
In November, we would like to draw your attention to a publication that examines public perception of the safety of nanomaterials in Austria.It shows, that although there is generally a rather positive attitude towards nanomaterials, there are different opinions on safety issues from different social groups. Further clarification seems necessary. Despite the widespread use of […]Read more
