What’s the latest on carbon nanotube safety?

Single walled carbon nanotubes

Just a few years ago, carbon nanotubes were front and center of discussions around the safety of engineered nanomaterials.  These days, not so much. So what happened?  Did we do the science and discover that they’re just as safe as any other form of carbon? Or did they simply slip off the safety radar? In ...

Who’s afraid of carbon nanotubes?

I’ve been fascinated by the coverage of Surrey nanosystems’ carbon nanotube-based Vantablack material this week. The material’s had widespread coverage – just Google “vantablack” to see what I mean.  But in amongst all the geeked-out media excitement over the world’s darkest material, there’s been nary a word on the possible health risks presented by the material. As ...

How safe is the world’s darkest material?

Vantablack – the new black? Over the past few days, the interweb’s been awash with virtual “oohs” and “ahs” over Surrey Nanosystems’ carbon nanotube-based Vantablack coating.  The material – which absorbs over 99.9% of light falling onto it and is claimed to be the world’s darkest material – is made up of a densely packed “forest” ...

Nanotubes create the blackest black – Douglas Adams would be proud

If your nanotechnology stream is anything like mine today, it will have been swamped by accounts like this one of “Vantablack” fabric – supposedly the world-s blackest-ever material! The material relies on a carbon nanotube forest that absorbs 99.965% of visible light that lands on it.  Putting aside the questions of safety, and how likely those ...
