As one who has closely followed the emergence of nanotechnology, I am sure I was not alone several years ago in welcoming what appeared to be a refreshingly new attitude among a broad range of stakeholders toward the introduction of this new set of technologies and materials.  Calls from my organization to “get nanotech right the first time” were echoed widely.  Perhaps the most frequently used metaphor, though, was that a “window of opportunity” had opened to do things differently this time.  But I increasingly fear that the window is closing.

In some nanotechnology circles, it is almost a mantra that, once released to the environment, nanoparticles will inevitably aggregate or agglomerate into larger masses and thereby lose their nanoscale-related properties and, by implication at least, any associated risks.

But can we count on nanoparticles released to the environment to self-regulate their own risk so conveniently? Read more »

Yesterday the U.S. House of Representatives overwhelmingly passed the National Nanotechnology Initiative Amendments Act of 2008 (H.R. 5940), by a vote of 407-6.  Among other changes, the bill calls for a number of much-needed improvements in how the NNI addresses health and environmental concerns associated with nanotechnology.  See EDF’s news release issued today.

Just when you thought it might never emerge, the National Nanotechnology Initiative’s (NNI) Strategy for Nanotechnology-Related Environmental, Health and Safety Research [2.2 MB PDF] finally hit the streets last week.

It’s got good, bad and ugly. The good news is that here, at last, is a report from NNI that actually reads more like a strategy and less like yet another laundry list of research needs. The bad news is that key elements of a full strategy are still nowhere to be found. Read more »
