Navigating the minefield of airborne nanoparticle exposure
Nanotechnology—like other emerging technologies—presents a dilemma: If you’re making new substances with uncertain health risks, how low is low enough when it comes to managing exposure?
The issue is raised in the current edition of Nature Nanotechnology by Vladimir Murashov of the National Institute for Occupational Safety and Health (NIOSH), and former NIOSH-director John Howard. But the question has been bubbling along for some time.
And it’s an important one. Uncertainty over safe workplace practices is bad news for nanotech businesses trying to do the right thing—especially small start-ups that don’t have the resources to work out their own bespoke solutions. It’s not much better for regulators—as the gap between emerging technologies and solid information on their safe use widens, how do you craft new approaches to protecting people’s health and the environment?

First impressions of the ICON EHS Database Analysis Tool
What do you do this holiday season when the turkey’s lost its appeal, you’ve seen every movie worth watching ten times over, and conversational déjà-vu sets in? If you are really desperate, you could play “nano-trivia”—and thanks to the fine folks at the International Council On Nanotechnology (ICON) you now have the perfect widget to help craft those cunning questions that will have your nearest and dearest wracking their brains.
Questions like “between 2000 and 2006, what percentage of scientific papers addressing the toxicity of carbon-based nanomaterials considered exposure via mucous membranes (or the skin)?”
OK, so maybe playing “toxic particle trivial pursuits” is the last resort of the desperate, and likely to result in an ever-decreasing circle of close friends. But for all that, the new ICON Environmental Health and Safety Database Analysis Tool has its merits… Read the rest of this entry »

Do emerging technologies have a place at the table?
As world leaders congregate in Washington DC this weekend for the G20 summit on the global financial crisis, discussions will be informed in part by what has been described as the “biggest brainstorming on the global agenda that has ever taken place.” I mention this because a small but nevertheless significant part of that brainstorm involved nanotechnology.
The brainstorm in question was the inaugural Summit on the Global Agenda, organized by the World Economic Forum and held in Dubai last weekend. The summit brought together “the 700 most knowledgeable people related to 68 global challenges” (WEF’s words) to address two questions… Read the rest of this entry »

UK Consumer Organization Which? Releases New Report
Who needs an emerging technologies blog when you have The Daily Mail? For those of you that missed it, Wednesday’s on-line issue of the British tabloid newspaper highlighted
“The beauty creams with nanoparticles that could poison your body”
I’m so glad someone’s tracking this issue, while us folks over on the other side of the pond are dealing with the considerably less-interesting issues surrounding the incoming Obama administration. The only trouble is, the Mail didn’t quite get it right. In fact on a scale of 1 – 10, I’m not even sure they even make it to first base… Read the rest of this entry »

Is the RBC Life Sciences® nanotechnology product Slim Shake approved for use by the US Food and Drug Administration (FDA)? According to the BBC Radio 4 science program Frontiers—broadcast on Monday evening—there may be some doubt. But I get ahead of myself.
The US-based company RBC Life Sciences® sells a range of dietary supplements and food products allegedly based on nanotechnology—8 of them are listed in the Project on Emerging Nanotechnologies public inventory of nanotech-enabled consumer products. As with many of the products in the inventory, it’s hard to tell whether they are truly using nanotechnology, and even harder to tell what steps have been made to assure their safety. But Monday’s edition of Frontiers shed a little light on this issue… Read the rest of this entry »

The silent rave might seem a rather bizarre social phenomenon; a group of strangers converging in a public place and dancing to their own individual iPod soundtracks. But I have a sneaking suspicion that the emerging technology community has been indulging in the new tech-equivalent of silent raves for some time now.
These suspicions are probably the delusional by-product of jetlag. But travelling back from the latest in a long line of multi-stakeholder nanotechnology meetings last week, the analogy hit a chord… Read the rest of this entry »

The blogging community is no stranger to the use (and possible abuse) of nanometre-scale silver—products ranging from silver-enhanced socks and toothpaste to plush toys and cure-alls have all appeared in the spotlight recently. With each passing month, the number of nano-silver gizmos on the market is growing.
Back in March 2006 when the Project on Emerging Nanotechnologies Consumer Products Inventory was launched, there were 25 products claiming to use nanoscale silver. In contrast, the August 2008 update of the inventory brought the number of nano-silver containing products to 235—an increase of nearly ten times over two and a half years!
