Summary of the report:

  • New laws are needed to ensure that vanishingly small particles made by the

    nanotechnology industry do not pose a threat to humans or the environment,

    experts said yesterday.
  • A government-backed report into nanotechnology from the Royal Academy of

    Engineering and the Royal Society, Britain's most prestigious scientific

    body, found that while nanotechnology is expected to bring about significant

    advances in healthcare, transport and electronics, nanoparticles could be a

    cause for concern.
  • Ann Dowling, the Cambridge University professor who chaired the group

    behind the report, said: "Where particles are concerned, size really

    does matter.
  • Nanotechnology, which describes the manufacture of devices and materials

    measuring billionths of a metre across, is already used to make nanoparticles

    for sunscreens and cosmetics.
  • In sunscreens, nanoparticles are used because they absorb and reflect UV

    rays while appearing transparent to the naked eye.
  • Concerns surround nanoparticles because they may be inhaled or absorbed

    through the skin with unforeseen health consequences.
  • The report recommends that because they can behave so differently from

    known materials, nanoparticles, often defined as particles measuring less

    than 100 billionths of a metre wide, and nanotubes, sheets of molecules

    wrapped into tiny tubes, should be treated as new substances under European

    and UK safety legislation.
  • To address the lack of understanding of the potential threats of

    nanoparticles, Prof Dowling called for the government to fund £6m of

    research into their toxicity and how they may build up in bodies and the

    environment.
  • "Unless a meaningful debate gets under way soon, nanotechnology has

    the potential to turn into the next GM,
  • with scientists forced to defend themselves against an anti-science

    backlash.
