“’Safe-by-design’ and ’toxic-by-design’ – two strategies for creating novel nanomaterials“
Nanotechnological revolution is expected to provide the analogous impact to the society as the introduction of the internet: new developments are seen and to be seen practically in all areas, from health-care to energy. ’Safe-by-design’ strategy for nanomaterials (NMs) was first introduced about 10 years ago, primarily due to the societal concern on safety of nanoproducts rapidly entering consumers market despite of scarce information on their potential toxicity and ecotoxicity. Currently it is self-evident that it is wise to synthesise novel nanomaterials that would not cause harm to their producers and the environment but still bare the ‘nano’-enabled properties such as high surface energy, new optical properties etc.
In 2004, Lab of Environmental Toxicogy at NICPB was within first teams in the world that started to work on toxicological effects of metal-based nanomaterials, e.g., by providing data on their toxicity and toxicity mechanisms – information of utmost importance for creation of safe NMs. Moreover, we have introduced the ’toxic-by-design’ concept, i.e. to convert negative properties of certain NMs (such as high toxicity) into useful ones as the mankind needs efficient biocides and antimicrobials. The presentation will illustrate both strategies and provide wider background for understanding the toxicity mechanisms of synthetic NMs. Our model systems are in vitro mammalian cell cultures, natural and recombinant bacteria, yeasts and aquatic risk assessment key species (algae, daphnids, protozoa) accompanied by various chemical and physical techniques.
14:00 Professor Maarja Kruusmaa (TTÜ, Centre for Biorobotics)
“From natural science to technology. And back again”
Centre for Biorobotics is conducting research on the interface of natural science and technology, investigating natural phenomena to build better technology and the other way around, use this technology to better understand the natural phenomena. In particular, we present some cases where we developed technology based on analogy with marine animals and used it to investigate aquatic animals and natural flows.
