The New Toxicology of Sophisticated Materials: Nanotoxicology and Beyond

by Andrew Maynard February 9, 2011

Cross-posted from The Risk Science Blog Several months ago, I was asked by a colleague if I fancied co-authoring a review on nanotoxicology for a copy of Toxicological Sciences celebrating the 50th anniversary of the Society of Toxicology (coming out later this year). Fool that I am, I agreed.  Interestingly though, as I and my [...]

Nanotechnology, climate and energy: over-heated promises and hot air?

by Andrew Maynard November 16, 2010

Friends of the Earth have just released a new report challenging claims that nanotechnology will lead to greener, more energy-efficient technologies, lower-impact technologies. I’ve only had the chance to skim through the report so far, and so don’t have detailed comments on it.  But on my initial skim a number of things struck me:

International Handbook on Regulating Nanotechnologies – sneak peak of contents

by Andrew Maynard November 4, 2010

Back in the mists of time, I was approached with a crazy proposition – would I help co-edit a book on nanotechnologies regulation!  In a moment of weakness I said yes, and a little more than two and a half years later, the book is finally about to hit the shelves. I actually think the [...]

Nanotechnology prominent in percieved 21st century science & engineering advancements

by Andrew Maynard November 4, 2010

This image from the first US National Science and Engineering Festival attracted my attention this morning: It’s a wordle constructed from responses to the question “What will be the greatest discoveries and advancements science and engineering will bring us in the 21st century?” What grabbed my attention was the prominence of nanotechnology in the mix [...]

Lost in the Maize

by Andrew Maynard October 29, 2010

A weekly reflection on life in academia Most of this last week was spent in San Francisco, at the NISE Net (Nanoscale Informal Science Education Network) network-wide meeting – possibly my favorite meeting of the year (I might have mentioned that before).  This year I had the additional pleasure of opening the meeting in a [...]

Limited resources and emerging technologies: China does the math

by Andrew Maynard October 20, 2010

New technologies depend on uncommon materials, and society depends on new technologies.  Which means that economies that develop the former and control the latter have something of an upper hand in today’s interconnected and technology-dependent world. This has clearly not escaped the notice of the Chinese.  China, which controls around 90% of the world’s rare [...]

Nanotechnology 2.0: The next ten years of nano risk research

by Andrew Maynard October 13, 2010

Sometime in the past couple of weeks – I’m not entirely sure when as accounts are conflicting – the World Technology Evaluation Center (WTEC) posted a draft of a new report examining the long-term impacts and research directions of nanotechnology.  The “Nano2″ study was supported by the National Science Foundation under the direction of Mike [...]

Realizing dreams of carbon nanotubes

by Nanocomp September 28, 2010

A guest blog by John Dorr, Vice President of Business Development Nanocomp Technologies Inc. Despite all the fuss over nanotechnology, it’s surprisingly difficult to get a clear sense of how the technology is contributing to new products.  So when the company Nanocomp Technologies Inc. approached me with an idea of writing a guest blog about [...]

Is nanotechnology suffering from “silent rave” syndrome?

by Andrew Maynard August 26, 2010

I couldn’t resist finishing the August in the Archives series with this piece on “silent rave” syndrome, which I am sad to say still seems to inflict the emerging technologies community! Originally posted October 5 2008 The silent rave might seem a rather bizarre social phenomenon; a group of strangers converging in a public place [...]

Value-added nanotechnology

by Andrew Maynard August 24, 2010

The more the debate over what precisely nanotechnology is goes on, the more inclined I am to think that it’s something of an illusion.  Sure, nanoscale science is real.  And there are clearly technologies that exploit this.  But are they nanotechnologies, or are they simply clever uses of science, technology and engineering across multiple length [...]

Nano-sunscreens leave their mark

by Andrew Maynard August 19, 2010

Most manufacturers of nanomaterial-based sunscreens try to make sure that the material they use doesn’t generate harmful chemicals in the presence of sunlight.  But the paper this piece was based on suggested that some photoactive materials might be slipping through the net. Originally posted June 21 2008. Painted metal roofs are cheap, convenient, and usually [...]

Enough meetings already!

by Andrew Maynard August 10, 2010

I couldn’t resist reposting this piece, as it captured so well my frustration at the time of spending so much time in meetings – usually for someone else’s benefit.  Sadly, I didn’t learn the error of my ways – my travel schedule has, if anything, got worse since then! Originally posted May 8 2008. My [...]

I’m breathing in nanoparticles, so why aren’t I dead already?

by Andrew Maynard August 5, 2010

This was based on a piece I originally wrote for Nano Today – the blog was a slightly extended version of what was published.  Although it was written two years ago, it’s still surprising how few people realize that breathing in nanoparticles is an everyday fact of life, and that to make sense of new [...]

ASME launches a new series of nanotechnology podcasts

by Andrew Maynard July 7, 2010

ASME – the organization that used to be known as the American Society of Mechanical Engineers – has just launched a series of educational podcasts on nanotechnology that are well worth checking out. Between now and next February, the ASME Nanotechnology Institute will be posting new video and/or audio podcasts on their website every couple [...]

Just how risky could nanoparticles in sunscreens be?

by Andrew Maynard June 8, 2010

Following up from my previous post, here’s an open question to Friends of the Earth: What is your worst case estimate of the human health risk from titanium dioxide and/or zinc oxide nanoparticles in sunscreens? What I am interested in is a number – a probability of a specific human health impact being caused by [...]

Friends of the Earth come down hard on nanotechnology – are they right?

by Andrew Maynard June 8, 2010

Friends of the Earth (FoE) do not like nanoparticle-based sunscreens.  This has been evident for some years – back in 2006 the organization published the report Nanomaterials, Sunscreens and Cosmetics: Small Ingredients, Big Risks, and every year since then they have had something to say on the subject. This year’s web-based piece leaves now doubt [...]

Nano Dispersants and nano hysteria – time to think about the science folks!

by Andrew Maynard May 28, 2010

Catching up with my email after a long day off the net, I see that a group of Non Government Organizations (NGOs) are urging EPA not to allow the use of an alleged nanotechnology-based dispersant in the Gulf of Mexico.  The letter from thirteen organizations was covered in a piece by Andrew Schneider on AOL [...]
