Opportunities and risks of nanotechnologies

Nanotechnologies are described as the key technology of the 21st century. We have to assume that they will bring dramatic changes to our everyday lives, and will also impact on the environment. There are already over 200 nanoproducts and some 600 nanomaterials or additives on the global market. In Switzerland, too, there are sun creams and toothpastes that contain nanoparticles, and the antibacterial effect in some fabrics and toys is the result of nanotechnology. In the future, drugs, for example, could target cancer cells directly, or materials that are micro-sized insulators but nanosized conductors could be used as efficient energy carriers. It seems that the potential applications are boundless. The International Association of Nanotechnology has estimated that in 2006 global investment in nano research and development will amount to around 4.3 billion US dollars. So naturally, “nano” has also become a good selling point. But just because it says “nano” on the label (as with the “iPod Nano”, or “Nano-Magic” household spray), it does not necessarily mean that there is actually any “nano” inside.

But at the same time, there are also some products that contain nano-sized substances but do not specifically declare them. Regulations about handling nanoparticles still have to be formulated. In Switzerland, the FOPH and the FOEN are developing an “Action plan on synthetic nanoparticles 2006 – 2009”. There is an urgent need for this, because toxicological studies on synthetically produced nanoparticles have indicated possible health risks. What may be harmless as a microparticle (one millionth of a metre in size) may have serious effects on human beings and the environment as a nanoparticle. Researchers, industrialists, government agencies and insurers are, however, unanimous: much more research has to be done in the nanoscience and nanotechnology fields on the possible toxicity of certain nanoparticles and the consequent potential risks for human beings and the environment.

Nanotechnological developments have the potential to change key areas of life in our society over the coming years and decades. This will also impact on ecological systems. As yet, there is little public awareness about nanotechnologies. In Switzerland, too, it is only recently that a coordinated approach has been initiated to takle questions of regulation. Political groups are paying close attention to the technical developments. Studies help to weigh up the opportunities and risks. Any legislation that may be necessary, however, must also take the views of the population into account. How do so-called “laypersons” perceive the nanotech debate? Where do citizens see opportunities for themselves, their health and the environment? And where do the possible risks lie? Does nanoresearch cross ethical boundaries? Is there a need for regulation or a standardised declaration? These are questions that TA-SWISS wanted to discuss with randomly selected citizen groups. Publifocus events are to be held in all parts of the country during September 2006.

Findings

The participants’ views – the results of the publifocus events, that is – are compiled into a report. This will be published towards the end of 2006 with the aim of informing interested members of the public – and members of parliament, as it is they who will have to decide whether there is likely to be any need for legislation as a result of developments in nanoscience and nanotechnology and their applications.
