Amidst the cacophony of debate swirling around the true meaning of nanotechnology, I head a voice or reason last week. The voice was that of Dr. Bernd Sachweh of BASF, speaking at the European Aerosol Conference in Thessoloniki.
I paraphrase, but the essence of Bernd’s point was this:
‘Nano’ is not a thing or a product. It has no intrinsic value. Rather, ‘nano’ adds value; it changes the properties and the worth of something that already exists.
I must confess, I rather like the idea of ‘nano’ as adding value, rather than being an entity in and of itself. It’s hard to come up with of an example where engineering something at the nanoscale leads to behaviour or functionality that is independent of the starting material. Rather, the great potential of nanotechnology would seem to be in taking raw materials and engineering them in ways that lead to the emergence of novel scale-related properties, which can then be used in new and innovative ways.
But what I really like about the concept of added-value is that it provides insight into how nanotechnology might be approached from an oversight perspective. Read the rest of this entry »

As the rate of technological progress advances, are we learning the lessons of past successes and failures? And are we applying these lessons successfully to nanotechnology?
In 2001, the European Environment Agency (EEA) published a seminal report on developing emerging technologies responsibly. Through a series of fourteen case studies spanning the past century, a panel led by the late Poul Harremoës examined what has gone right and what has gone wrong with the introduction of past technologies, and what can be learned about introducing new technologies as safely and as successfully as possible.
The resulting report, “Late lessons from early warnings: the precautionary principle 1896-2000” (PDF, 1.7 MB) draws twelve “late lessons” for decision-makers faced with addressing emerging technologies . Read the rest of this entry »

“Nanotechnology” as an overarching concept is great for sweeping statements and sound bites, but falls short when it comes to real-world decision-making. As nanoscale technologies are increasingly used in everything from antimicrobial socks to anti-cancer drugs, perhaps its time to rethink how we talk about the myriad diverse technologies that fall, slip or are forcibly squeezed under this all-encompassing banner.
