Nano-scale technology is a suite of techniques used to manipulate matter at the scale of atoms and molecules. “Nano” is a measurement – not an object. Unlike “biotechnology,” where you know that bios (life) is being manipulated, “nanotechnology” speaks solely to scale. A “nanometre” (nm) equals one billionth of a metre. One human hair is about 80,000 nanometres thick. It takes ten atoms of hydrogen side-by-side to equal one nanometre. A DNA molecule is about 2.5 nm wide. A red blood cell is vast in comparison: about 5,000 nm in diameter. Everything on the nano-scale is invisible to the unaided eye and even to all but the most powerful microscopes.
Geneva -- “The actions on nanotechnology that were agreed upon today do not reflect the urgency of the issue. The delegates were made aware that nanomaterials are an intergenerational risk, with nanoparticles being passed from mother to child via maternal blood. Yet these risks appear to have been ignored in the response by ICCM2," said Dr. Mariann Lloyd-Smith, IPEN CoChair.
“We are a long way from the statement that was adopted less than a year ago at the meeting organized by the International Forum on Chemical Safety in Dakar,” said Diana Bronson from ETC Group. “There, governments, industry, trade unions and non-governmental organizations had agreed that the precautionary principle needed to be applied, that countries should have the right to say no to nanotechnology and that special measures need to be taken to protect vulnerable groups. We got none of that in Geneva.”
Now that you can drive your ‘nano’ car, listening to your iPod ‘nano’ while wearing ‘nano’ sunscreen and ‘nano’ clothing, the UK’s largest organic certifier has just introduced the perfect nano-antidote – a ‘nano-free’ standard for consumer products. The Soil Association – one of the world’s pioneers of organic agriculture – announced today that it is has banned human-made nanomaterials from the organic cosmetics, foods and textiles that it certifies.

In the name of moving “beyond petroleum,” Big Oil, Gene Giants, governments, start-ups and others are forming partnerships that will extend corporate control over more resources in every part of the globe – while keeping the root causes of climate change intact. With grudging recognition that first-generation agrofuels are neither economical nor ecological, investors turn to other life-based technologies, including synthetic biology, for the next alternative fuel fix.
