Thanks to Howard Lovy for using a quote from me in his Wall Street Journal article. The article was about reactions to the Royal Society report on nanotechnology, Nanoscience and nanotechnologies: opportunities and uncertainties, and my quote said something like: “Good news for the environment, good news for nanotechnology, bad news for lab rats”. Underneath this flippant sounding response there is, I think, a serious point aboout the way the report marked the emergence of a strange alliance between nanoscientists and environmentalists. The effect of this unlikely alliance has been to focus the nanotechnology debate almost exclusively on a single topic, the possible toxicity of nanoparticles, and certainly the headline reactions to the report have been to focus on its recommendations for tightened regulation of the use of nanoparticles and for more research on their toxicity. I’m not saying that it isn’t a good idea to do both of these things; it is, and the measures the report calls for are entirely sensible. But you don’t have to be a fervent devotee of Drexlerian MNT to wish that the report, and more importantly the press reaction to it, had focused a bit more on the longer term, both in terms of potential benefits, and in terms of the more far-reaching social implications raised by issues such as universal surveillance and human enhancement.
What has led to this alliance of convenience? The idea of nanoparticles posing an environmental toxicity risk is of course one that fits very well in the environmental movement’s long running narrative about the chemical industry, so that’s an issue they are very comfortable about highlighting. The reason for reaction of the nanoscientists is more interesting. The issue is very contained, very tractable, and rather easy to suggest remedies for – a bit more regulation and a few more rats sacrificed in toxicology studies. And from an academic point of view, the subject is a little bit boring. The glamorous areas of nanoscience – the ones that get papers in Nature and Science – are in areas like molecular electronics, biological molecular motors, new applications of nanomagnetism, and suchlike. Making nanoparticles is now really a chemical engineering issue, so mainstream nanoscientists may not be that bothered if a few more obstacles are thrown in its commercialisation path.
