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 ...

Nanoparticles in baby formula: should parents be worried?

Nanoparticles in baby formula

There’s a lot of stuff you’d expect to find in baby formula: proteins, carbs, vitamins, essential minerals. But parents probably wouldn’t anticipate finding extremely small, needle-like particles. Yet this is exactly what a team of scientists here at Arizona State University recently discovered. The research, commissioned and published by Friends of the Earth (FoE) – ...

For tech innovation to succeed, we need parallel innovation in how we think about risk

For tech innovation to succeed, we need parallel innovation in how we think about risk

In October 2014, Google announced it was working on an innovative nanotechnology-based approach to avoiding and managing disease. The idea was to create a pill that would deliver magnetic, functionalized nanoparticles from the gut to the bloodstream. Once there, they would circulate — presumably for days, or longer — picking up biomarkers of disease along ...

Characterizing nanoparticles in the 1880’s

Characterizing nanoparticles in the 1880s

On May 29th, there were 52,000 nanoparticles per cubic centimeter of air measured at the top of the Eiffel Tower. This may not seem the most compelling opening to an article, until you realize that the measurement was made in 1889 – over 100 years before nanotechnology and nanoparticles began hitting headlines as one of the most talked about emerging technologies in recent decades. The particles were measured by the Scottish scientist John Aitken, using his newly developed device for counting airborne dust particles.

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 ...

Nano silver and ebola: Show us the data, or remove claims (FDA)

On September 23, the Food and Drug Administration sent Rima Laibow and Ralph Fucetola at the Natural Solutions Foundation a warning letter claiming that their allegedly nano (colloidal) silver based “Dr. Rima Recommends™ The Silver Solution” product violates the Federal Food, Drug, and Cosmetic Act (FFDC Act). Earlier in September, I wrote about Rima Laibow’s promotion of the use of ...

Using nano silver to treat Ebola – is it misguided?

Update Oct 2: With concern over ebola in the US growing, I’m seeing a number of websites advocating the use of colloidal or nano silver as an effective preventative or cure.  Just to be clear – there is no research that suggests ingesting colloidal silver is any more effective than wishful thinking in treating or ...

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 ...

Advanced Materials – What’s the big deal?

Why are materials important? How do they limit what we can achieve? And what can we do to change this?  (Check out the videos below). Advanced Materials Materials and how we use them are inextricably linked to the development of human society.  Yet amazing as historic achievements using stone, wood, metals and other substances seem, these ...

Six years of nanoparticle sunscreen safety scribblings

I was going through the 2020 Science archives the other day looking for pieces on nanoparticles and sunscreens, and was rather shocked to see that the earliest article dates back to 2008! Here they are in chronological order – surprising how little things change with time!  The 2010 exchange with Friends of the Earth is definitely ...
