Seven challenges to regulating “sophisticated materials”

by Andrew Maynard July 22, 2011

The materials that most current regulations were designed to handle are pretty simple by today’s standards. Sure they can do some nasty things to the environment or your body if handled inappropriately. And without a doubt some of the risks associated with these “simple” materials are not yet well understood – especially when it comes [...]

US government kicks nanotechnology safety research up a gear

by Andrew Maynard February 18, 2010

It looks like the US is heading for some serious action on addressing the safe development and use of nanotechnology-enabled materials, products and processes in 2011.  Reading through the just-released National Nanotechnology Initiative’s (NNI) Supplement to the President’s 2011 budget [PDF, 1.2 MB], there are some noteworthy inclusions:

24 questions and answers on nanotechnology safety

by Andrew Maynard February 12, 2010

Well I guess I set myself up good and proper – I should have realized that in asking people for their questions on nanotechnology safety last week, they would actually want answers! Having failed miserably to compile a catalog of websites that provide clear and concise answers to the questions asked in last week’s blog [...]

Twenty nanotechnology safety questions in search of answers

by Andrew Maynard February 5, 2010

I should warn you in advance – this is an interactive blog – there’s something I want from you!  I have a question – where do ordinary people go to get information on nanotechnology safety? Feeling a little lazy I thought I would get you – the loyal 2020 Science readership – to help me [...]

Nanotechnology researchers at sea when it comes to safety

by Andrew Maynard February 2, 2010

If you ever wanted proof that the nanotechnology research community is floundering when it comes to safe working practices, look no further than a paper just published in the journal Nature Nanotechnology.  The paper, written by researchers at the Nanoscience Institute of Aragon (NIA) in Spain, surveys nanosafety practices in labs around the world.  Sadly, [...]

Could some nanoparticles inflict harm across normally tight biological barriers?

by Andrew Maynard November 5, 2009

A new paper published on-line today in Nature Nanotechnology hints that some nanoparticles could cause damage to cells on the other side of normally tight barriers – such as the blood brain barrier or the placenta – without actually crossing the barriers.  It’s a study that could raise concerns over the safe  medical use of [...]

Want the low-down on nanotechnology safety? Try these ten helpful resources

by Andrew Maynard September 14, 2009

Where’s the best place to look for down to earth information on nanotechnology safety?  Surprisingly, given how much time I spend speaking and writing about the subject, I don’t think I have ever sat down and compiled such a list.  But while preparing for this year’s annual meeting of the Nanotechnology Informal Science Education Network [...]

Helter skelter nanotechnology

by Andrew Maynard September 5, 2009

There’s an absolute killer of a nanotechnology blog post over on placescope, if you are looking for something to brighten your day.  It appears to be based on some old Project on Emerging Nanotechnologies (PEN) press releases.  But the process of translation and re-translation has rendered them so wonderfully bizarre as to make any connection [...]

Ten things everyone should know about nanotechnology safety

by Andrew Maynard August 29, 2009

Asked to conclude the Fourth International Conference on Nanotechnology, Occupational and Environmental Health in Helsinki this year, I rather rashly came up with the above title for my talk—thinking that I would find inspiration in the multitude of new research on nanotech safety being presented at the meeting. As it turns out, events conspired against [...]

New study seeks to link seven cases of occupational lung disease with nanoparticles and nanotechnology

by Andrew Maynard August 18, 2009

A new study about to be published in the European Respiratory Journal links workplace nanoparticle exposure to seven cases of serious and progressive lung disease in China – leading to two patient deaths – and presses a number of “hot” buttons when it comes to the safety of emerging nanotechnologies. To help place the study [...]

Nanoparticle exposure and occupational lung disease – six expert perspectives on a new clinical study

by Andrew Maynard August 18, 2009

The recent tragic account of seven Chinese workers suffering—apparently—from nanoparticle-induced lung disease, is likely to raise serious concerns with anyone potentially exposed to similar particles.  Yet without the benefit of insight from scientists and others working on nanoparticles and their potential health impacts, it’s hard to get a handle on the study’s broader relevance. When [...]

Is nanotechnology poised for the ride of its life?

by Andrew Maynard August 18, 2009

In the wake of a new study linking “nanotechnology” to two deaths and five additional cases of lung disease, the emerging technology of the ultra-small could be in for a rough ride.  Yet the real risk is that in the rush to use or even abuse the findings, the science and it’s true relevance are [...]

Nanotechnology: Ensuring success through safety

by Andrew Maynard June 16, 2009

This month’s issue of the magazine Science & Technology takes a closer look at some of the controversies, dilemmas and decisions that will impact on the future development of the science and technology of working at the nanoscale.  Amongst the commentaries is a short piece I wrote about the importance of safety in underpinning successful [...]

Working safely with carbon nanotubes

by Andrew Maynard March 17, 2009

So you want to make or use carbon nanotubes, but you are worried about handling then safely.  What do you do?  The good news is that the UK Health and Safety Executive has just published an information sheet that addresses just this question.  Risk management of carbon nanotubes is (according to the blurb) “specifically about [...]

Asbestos-like nanomaterials – should we be concerned?

by Andrew Maynard January 23, 2009

I’m afraid the “A” word just won’t go away.  It seems that every time people start thinking about the possible health effects of long, thin, fibrous nanomaterials, the question pops up “is this the next asbestos?”  You’d have thought that the issue would have been resolved by now—after all, nanomaterials like carbon nanotubes have been [...]

Indecent exposure

by Andrew Maynard December 1, 2008

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 [...]

Nano-silver: Old problems or new challenges?

by Andrew Maynard September 9, 2008

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.

Nano-sunscreens leave their mark

by Andrew Maynard June 21, 2008

Painted metal roofs are cheap, convenient, and usually very durable.  But over the past two years, a rash of accelerated ageing has blighted pre-painted steel roofing in Australia.  And intriguingly the ageing—which affects the coating—seems to be localized to small patches, taking on the form of fingerprints, handprints and even footprints. The culprit it seems [...]

U.S. nanotechnology risk research funding—separating fact from fiction

by Andrew Maynard April 18, 2008

The most recent estimate from the U.S. National Nanotechnology Initiative (NNI) puts nanotechnology risk research investment at $68 million for 2006 (the only year complete figures are currently available for—apparently).  Yet theProject on Emerging Nanotechnologies (PEN) has just completed its own assessment—and could only find $13 million associated with research projects primarily focused on addressing nanotechnology risk in [...]
