The smallest particles in materials research, nanoparticles, have occupied us intensively for more than 20 years to elucidate and further investigate their safety for humans and the environment. Now, however, the development is going from “small = nano” to “clever = advanced”, as discussed in a contribution by international scientists. Thereby, it is a great advantage to learn directly from the developments and achievements in the safety research of nanomaterials or to be able to transfer and apply them to advanced materials as well. In addition to the question “What is actually advanced or smart”, the demand for “Safe and sustainable by design (SSbD)” is also raised and the associated challenges are addressed. Important criteria for research here are the possibilities of characterizing the object of investigation, i.e. the concrete description of an advanced material, as well as the quality of the data generated and the data management. Again, the need for close collaboration between scientists from different disciplines with other stakeholders such as industry or regulatory authorities is pointed out. The authors make the important observation that nanosafety research to date has provided and will further provide the tools to meet this new challenge as well.
In doing so, they draw attention to three important prerequisites:
- The extension from “nano” to “advanced materials” should be based on technical criteria and include modelling as well as grouping approaches.
- Furthermore, sustainability should be integrated into the new material designs.
- And finally, these two principles should be firmly anchored in research, innovation and regulation to ensure a smooth transition to the implementation of the new and innovative materials.

Spotlight October 2021: Nanopesticides – a proposal for a risk assessment framework
The application of so-called “nanopesticides” (see also cross-sectional text Nanomaterials in plant protection products) is said to have two basic advantages: a smaller amount of pesticide is needed for the same agricultural area and the efficacy is improved. This is necessary to grow enough food for a still growing world population. However, this could also […]Read more
Spotlight June 2021: Endotoxin – the reason for false-positive toxicity testing for advanced materials?
Advanced materials, but also nanomaterials are closely examined to determine whether they trigger biological effects that could be harmful to humans and the environment before they are used in products. This also includes such materials as titanium dioxide, which has been used in a wide variety of products for more than 50 years. A particularly […]Read more
Spotlight October 2022: The titanium dioxide debate – why the current ECHA and EFSA hazard classification should be questioned
Due to various reports and scientific studies, titanium dioxide (TiO2)was also banned in Europe this year (2022) for use as a food additive with the indication that it could possibly be carcinogenic to humans. Although no case of tumour induction in humans has been reported since the use of this material in micro but also […]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
