Navigating the nanotechnology risk landscape – pointers for early career scientists

Navigating the risk landscape that surrounds nanotechnology development can be a daunting task – especially if you are an early career researcher just getting started in the field.  There are plenty of studies and speculations around what might – or might not – be risky about nanoscale science and engineering.   But surprisingly, there are relatively ...

Is novelty in nanomaterials overrated when it comes to risk?

Novelty and nanotechnology are deeply intertwined. The search for nanostructure-enabled materials has driven research funding in nanotechnology for well over a decade now; the exploitation of novel properties has underpinned the commercialization of nanomaterials; and concerns over potential risks has stimulated widespread studies into what makes these materials harmful. Yet ‘novelty’ is an ephemeral quality, and despite its close association with nanotechnology, it may be an unreliable guide to ensuring the long-term safety of materials that emerge from the field. If this is the case, do we need to find alternative approaches to developing advanced materials and products that are safe by design?

A decade of uncertainty in nanoscale science and engineering

First published in Nature Nanotechnology, 5 March 2014.  Nature Nanotechnology 9, 159–160 (2014) doi:10.1038/nnano.2014.43 [Link] Ten years after the publication of an influential report on the uncertainties in nanoscale science and engineering, are we in danger of creating a new metaphorical grey goo? In 2004, the Royal Society and Royal Academy of Engineering (RS-RAE) in the ...

Fumed silica: Another nano material we need to worry about?

Pick up a jar of chili powder, and the chances are it will contain a small amount of fumed silica – an engineered nanomaterial that’s been around for over half a century.  The material – which is formed from microscopically small particles of amorphous silicon dioxide – has long been considered to be non-toxic. Amorphous ...

Q&A on Nanotech regulation in Europe

Chemistry World posted a good article yesterday on nanotech regulation in Europe (Europe mulls best way to handle nanotech by Andrew Williams).  I have a couple of quotes in the piece, along with Risk Science Center colleague Diana Bowman).  These are taken from a longer set of responses to questions from Williams, which I thought it might be ...

EC adopts cross-cutting definition of nanomaterials to be used for all regulatory purposes

The European Commission had just adopted a “cross-cutting designation of nanomaterials to be used for all regulatory purposes” (link). The definition builds on a draft definition released last year, but includes a number of substantial changes to this. Here’s the full text of the definition:
