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 January 2021: Nanoplastics challenge – How to improve tracking of nanopolystyrene distribution in the environment.
In January, we present a paper published in the Nature Journal communications materials. The article focuses on the development of a new detection method of nanopolystyrene. The method not only makes it possible to detect nanoplastics in the environment for the first time, but also to determine their accumulation in plants and animals. Nanoplastics, which […]Read more
Spotlight August 2022: Three-stage model for the formation of micro- and nanoplastic particles.
Plastic pollution is a global problem that will continue to affect humanity for more than 100 years. There is the visible pollution, e.g. plastic debris in the environment, which leads to death for many animals (because they mistakenly think the plastic is food and eat it or because they get caught in the plastic waste). […]Read more
Spotlight July 2021: The Path to Digital Material Research – It is never too late to start
Machine Learning, Artificial Intelligence, Big Data…. Have you read these words lately? No, these are not just buzzwords. The digitalisation of science is an evolving topic that is gaining importance with each passing day. That is why this month we would like to introduce you to the article “Digital Transformation in Materials Science: A Paradigm […]Read more
Spotlight December 2021: Silica nanoparticles improve plant disease resistance
The resistance of plants to various pathogens is often increased in agriculture with various chemicals (“fertilizers”). A new direction is being taken with the use of nanoparticles. These can be sprayed on the plants. In the present study, the model plant Arabidopsis was used to investigate whether silicon dioxide nanoparticles (SiO2) can increase resistance to […]Read more
