The Scientific Reality behind Nanotechnology

28.07.2003


Nanotechnology is an emerging range of technologies in which medicine and engineering meet physics and chemistry. Nanotechnology supporters claim that the machines and materials it may produce will mean faster computers, less pollution and cheaper energy, and longer and healthier lives.



Critics, however - from Prince Charles to Jurassic Park author Michael Crichton - fear that nanomachines could run amok and turn the surface of the Earth into an uninhabitable morass. Environmentalists also question the safety of nanoparticles.

The debate, like that on genetically modified food, is noisy but often uninformative. Before the technology has even emerged, the debate has largely become polarised into utopian and dystopian visions.


In a report published today (28th July 2003), a team at the University of Sheffield funded by the Economic and Social Research Council investigates the scientific reality behind nanotechnology, and looks at the hopes and the fears that it raises - and provides a sober assessment of the possibilities that will help both sides of the debate.

The Social and Economic Challenges of Nanotechnology is the result of collaboration between a social scientist and a natural scientist: Professor Stephen Wood of the ESRC Centre of Innovation and Organisation (COI), and Professor Richard Jones of the Department of Physics and Astronomy, with Alison Geldart (COI), all at the University of Sheffield. It describes the emerging atom-by-atom science of nanotechnology and discusses the sweeping social and economic changes it might bring.

The word nanotechnology has been used to refer to everything from mundane, here and now applications, like stain-resistant trousers, to the most speculative extrapolations, such as self-replicating nano-robots. The report carefully distinguishes between what these technologies are delivering now, what may be possible in the future, and what is likely to remain beyond the bounds of feasibility.

The role of social science in nanotechnology´s development should be more than one of smoothing the path for its acceptance. Social science can help construct the lens (or lenses) through which we see nanotechnology, and understand its implications so these can be anticipated and incorporated into development.

Nanotechnology is also an opportunity to investigate broader themes, such as an evaluation of the drivers behind the technology development process, how society deals with risks under uncertainty, and issues of inequities and economic divides.

Easily readable, the report serves as a primer for those wanting to know what nanotechnology means. For those already engaged in the technology, boosters and doubters alike, it will become a major reference.

Im Focus: BAM@Hannover Messe: innovative 3D printing method for space flight

At the Hannover Messe 2018, the Bundesanstalt für Materialforschung und-prüfung (BAM) will show how, in the future, astronauts could produce their own tools or spare parts in zero gravity using 3D printing. This will reduce, weight and transport costs for space missions. Visitors can experience the innovative additive manufacturing process live at the fair.

Powder-based additive manufacturing in zero gravity is the name of the project in which a component is produced by applying metallic powder layers and then...

Im Focus: Molecules Brilliantly Illuminated

Physicists at the Laboratory for Attosecond Physics, which is jointly run by Ludwig-Maximilians-Universität and the Max Planck Institute of Quantum Optics, have developed a high-power laser system that generates ultrashort pulses of light covering a large share of the mid-infrared spectrum. The researchers envisage a wide range of applications for the technology – in the early diagnosis of cancer, for instance.

Molecules are the building blocks of life. Like all other organisms, we are made of them. They control our biorhythm, and they can also reflect our state of...

Im Focus: Spider silk key to new bone-fixing composite

University of Connecticut researchers have created a biodegradable composite made of silk fibers that can be used to repair broken load-bearing bones without the complications sometimes presented by other materials.

Repairing major load-bearing bones such as those in the leg can be a long and uncomfortable process.

Im Focus: Writing and deleting magnets with lasers

Study published in the journal ACS Applied Materials & Interfaces is the outcome of an international effort that included teams from Dresden and Berlin in Germany, and the US.

Scientists at the Helmholtz-Zentrum Dresden-Rossendorf (HZDR) together with colleagues from the Helmholtz-Zentrum Berlin (HZB) and the University of Virginia...

Im Focus: Gamma-ray flashes from plasma filaments

Novel highly efficient and brilliant gamma-ray source: Based on model calculations, physicists of the Max PIanck Institute for Nuclear Physics in Heidelberg propose a novel method for an efficient high-brilliance gamma-ray source. A giant collimated gamma-ray pulse is generated from the interaction of a dense ultra-relativistic electron beam with a thin solid conductor. Energetic gamma-rays are copiously produced as the electron beam splits into filaments while propagating across the conductor. The resulting gamma-ray energy and flux enable novel experiments in nuclear and fundamental physics.

The typical wavelength of light interacting with an object of the microcosm scales with the size of this object. For atoms, this ranges from visible light to...
