Spotlight May 2021: Towards safe and sustainable innovation in nanotechnology: State-of-play for smart nanomaterials
The European Commission’s new Action Plan for a Circular Economy Green Deal, the new European Industrial Strategy as well as the Chemicals Strategy for Sustainability presented in October 2020 are ambitious plans to achieve a sustainable, fair and inclusive economy in the European Union. These strategies require that any new material or product must not only be functional and cost-efficient, but also safe and sustainable.
Nanotechnology is one of the technologies that could enable such green growth. This paper focuses on nanomaterials that actively respond to external stimuli, so-called “smart nanomaterials”. They are part of the broader category of “advanced materials”. It shows that smart nanomaterials and related products may pose new challenges for safety and sustainability assessment due to their complexity and dynamic behaviour. Innovators, scientists and authorities are called upon to further develop and promote the concept of “Safe and Sustainable-by-Design” in nanotechnology.

When we, the DaNa team as operators of the website nanopartikel.info, write about nanobots, i.e. nanometre-sized machines, we point out that these machines belong to science fiction, may even remain a utopia – i.e. never realisable. On the significantly larger micro-scale, however, small machines are conceivable that could help in the therapy of diseases, e.g. […]

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 […]

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 moreSpotlight 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 […]
