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.

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.

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.

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.

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 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.

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.

It's unlikely that many nanotechnologists are familiar with diatoms - a group of single-celled shelled algae - but that could change following a world-first conference on diatom nanotechnology that's set to take place in the US in October. Liz Kalaugher spoke to conference organizer Richard Gordon of the University of Manitoba, Canada, to find out more.

As traditional silicon circuitry continues to shrink towards a point where it can no longer function, researchers are searching for alternative methods to develop smaller, faster, and smarter computer chips. Yong Chen explains his research group's recent work to create the memory circuits of the future.
