Living in a post-chemistry world – the regulatory challenges of emerging nanotechnologies

by Andrew Maynard September 11, 2009

Regulators around the world are currently grappling with how to manage the possible risks associated with first generation nanotechnologies.  But increasingly sophisticated nanotechnology-based products are coming – will the old regulations still cover these emerging nanotechnologies, or is a re-think in how substances are regulated in order?  These are some rough notes I prepared for [...]

Nanotechnology: Weighing the risks of regulation

by Andrew Maynard July 8, 2009

I’m often intrigued by the evolution of an article from its early drafts to the final version.  To complement today’s commentary on nanotechnology regulation in the journal Nature, written jointly with David Rejeski, I thought it would be interesting to post an early draft of the same paper here.  This is what the piece looked [...]

Nanotechnology: From nano-novice to nano-genius in 13 steps

by Andrew Maynard May 26, 2009

Back in April, the folks at the PBS station THIRTEEN asked me to answer 13 questions on nanotechnology and the environment for their website feature Green Thirteen.   The questions ended up covering most of nanotechnology – what it is, what it’s good for, what the downsides might be, and how we might overcome potential problems [...]

New carbon nanotube study raises the health impact stakes

by Andrew Maynard March 26, 2009

I’m looking at an electron microscope image of a carbon nanotube – as I cannot show it here, you’ll have to imagine it.  It shows a long, straight, multi-walled carbon nanotube, around 100 nanometers wide and 10 micrometers long.  There is nothing particularly unusual about this.  What is unusual is that the image also shows [...]

Confessions of a “media hog”

by Andrew Maynard March 26, 2009

There are some things they don’t cover in media training, like giving interviews while suffering from stomach flu, talking to reporters thousands of miles away while on a dodgy cell phone connection, or speaking intelligently while your three-year-old niece runs rings around your legs.  It’s probably because they come under the “so bloody stupid no [...]

New life, old bottles: The video

by Andrew Maynard March 25, 2009

A five-minute primer on the promise and challenge of first-generation synthetic biology As an addendum to the previous post on synthetic biology, the following interview from the Wilson Center provides a great overview of what synthetic biology is all about, and the potential challenges of ensuring its safe development and use: Get the Flash Player [...]

Are we ready for synthetic biology?

by Andrew Maynard March 25, 2009

A new report looks at the challenges of regulating first generation products of synthetic biology. At the J. Craig Venter Institute, scientists are on the verge of creating a living organism from “dead” chemicals, by rebooting a microbe with a new—and completely artificially constructed—genome. At the University of California Berkeley, researchers are modifying microbes to [...]

Nanotechnology risk research, ten years on

by Andrew Maynard March 2, 2009

Ten years ago to the month, one of the first research reports detailing the challenges of ensuring the safe use of engineered nanomaterials was delivered to the UK Health and Safety Executive.  The report wasn’t for general release, and you’ll be hard pressed to find a copy of it in the public domain.  But as [...]

A 2020 Science Taster

by Andrew Maynard February 19, 2009

Given the recent surge in 2020science readers (thanks to Lon S. Cohen at Mashable), I thought it about time I did a short retrospective—a taster for the type of stuff you can expect to read here.  So here are five pieces from the past year that cover everything from nanotechnology to synthetic biology, and ethics [...]

Biohacking—synthetic biology for the technologically marginalized

by Andrew Maynard December 26, 2008

Last June I wrote a short piece on biohacking, prompted by a UK report on the social and ethical challenges of synthetic biology.  At the time, I though the aspirations of the nascent biopunk community naively optimistic, but potentially worrying.  Six months on, biohacking is hitting the mainstream press—and gaining momentum. Maybe it was just [...]

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 [...]

Taking a fresh look at nanomaterials

by Andrew Maynard November 11, 2008

The Royal Commission on Environmental Pollution report on Novel Materials Imagine for one naïve moment that we have a pretty good handle on managing the environmental impact of existing manufactured “stuff”.  Then someone comes along and invents some “new stuff” that behaves very differently from the “old stuff.” How can we be sure that the [...]

Nanotechnology and cosmetics

by Andrew Maynard November 6, 2008

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 [...]

Resolving the carbon nanotube identity crisis

by Andrew Maynard October 31, 2008

Twelve months ago today I held a bag of multi-walled carbon nanotubes up before a hearing of the U.S. House Science Committee.  I wanted to emphasize the discrepancy between the current state of the science on carbon nanotubes, and a tendency to classify this substance as the relatively benign material graphite from a safety perspective.  [...]

Shaking up the nano-food debate

by Andrew Maynard October 20, 2008

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 [...]

Value-added nanotechnology

by Andrew Maynard September 3, 2008

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 [...]

Late lessons from early warnings

by Andrew Maynard July 20, 2008

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 [...]

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 [...]

Smart materials; smart choices?

by Andrew Maynard May 31, 2008

Why nano?  Why care?  For non-nanotech initiates, an obsession with nanotechnology must sometimes seem a bizarre occupation of the sad and lonely.  And even within the nanotechnology community, who hasn’t had occasional doubts over the legitimacy of singling out “nano” as something special?  Yet occasionally a piece of work comes along that helps put things [...]

Carbon nanotubes: the new asbestos? Not if we act fast.

by Andrew Maynard May 21, 2008

Mix carbon nanotubes and asbestos together (metaphorically) and you get an explosive mix—at least if news coverage of the latest publication coming out of Professor Ken Donaldson’s team is anything to go by.  The research—published on-line today in Nature Nanotechnology—is the first to explicitly test the hypothesis that long carbon nanotubes behave like long asbestos [...]
