Fujitsu makes a big push in nanotechnology

At Nanotech 2006 in Tokyo, Fujitsu showed off its progress in nanotechnology. Liz Kalaugher spoke to Naoki Yokoyama to find out more.

Nanoparticle size affects uptake by cells

Size and shape of gold nanoparticles alters their adsorption by cells.

Nanotechnology in the news

Nanotechnology has been the topic of intense media scrutiny. But how do nanoscientists feel about that coverage? A team from the University of Plymouth, UK, reports.

Seeing with electrons

Commercially available lens correctors are extending the reach of electron microscopes to unprecedented atomic scales, says Peter Nellist.

NanoJury gives its verdict

UK public engagement project delivers its recommendations for nanotechnology's future.

How to get up close to nanotech

New laboratories and courses devoted to nanotechnology are springing up all the time. Matin Durrani explores how to get into the field.

Friction at the nano-scale

Nanomachines will depend on our knowledge of friction, heat transfer and energy dissipation at the atomic level for their very survival.

The future of nanotechnology

Visions of self-replicating nanomachines that could devour the Earth in a "grey goo" are probably wide of the mark, but "radical nanotechnology" could still deliver great benefits to society. The question is how best to achieve this goal, as Richard Jones explains.

Quantum change for nanotubes

A metallic carbon nanotube can be made into a semiconductor and vice versa when a magnetic field is combined with a little quantum mechanics. Jing Kong, Leo Kouwenhoven and Cees Dekker explain.

Prince Charles airs his nano-views

The UK's Prince Charles has spoken out again on nanotechnology. Writing in The Independent on Sunday newspaper, Charles detailed his concerns that society won't pay proper attention to the risks the technology may bring.

Optical litho: there are no fundamental limits

Illuminating silicon wafers with a pattern of light has long been the process of choice for making microelectronics, but there are fears that it will not be able to meet future demands. Steven Brueck, a supporter of the technology, argues why it is here to stay.

Low-loss nanowires create a wealth of applications

Optical sensors, integrated circuits and photonic devices are just some of the applications set to benefit from nanowires made out of glass. Jacqueline Hewett speaks to the researchers pioneering the development of these ultra-fine fibres.

2003: nanotechnology in the firing line

2003 was the year when nanotechnology collided with the real world. It was a painful collision, bringing prophecies of doom, fears of hidden dangers and calls for a moratorium on nanoscience. But the appearance of an ethical dimension to nanotechnology may serve the useful purpose of forcing other emerging technologies to confront questions about public understanding and perceptions about social responsibility. And, for nanoscience in particular, it may help to sharpen views about what the field comprises and where it is headed. Philip Ball looks at what we have learnt from the year that “nano” hit the headlines, in a feature based on a talk he gave at the International Conference on Nanomaterials and Nanomanufacturing held at The Royal Society, London, UK, on 15-16 December 2003.

Ball-bearings for the 21st century

Quantum dots will be to this century what ball-bearings were to the last - the unseen enablers of a new era of human invention. So says Paul O’Brien, head of chemistry at Manchester University in the UK and founder of a company called Nanoco that manufactures these nanometre-sized lumps of semiconductor. Edwin Cartlidge finds out more.

UK working group scrutinizes nanotechnology

Back in June, the UK government commissioned an investigation into the implications of nanotechnology. Ann Dowling, chair of the working group carrying out the study, gives more details.
