Nanotechnology is ancient history

In the antiquities, nanoparticles were used by the Damascans to create swords with exceptionally sharp edges and the Romans to craft iridescent glassware. So were these archaic artisans also nanotechnologists? And what can today's scientists learn from such historic artefacts?<p>The ancient empires of …

Nanotechnology: striking a balance between glorification and 'grey goo'

Great things can happen when you think small: thousands of times smaller than a grain of sand, much finer than your thinnest hair. So small that swimming among water molecules would feel as though you were in a pool of thick jam.<p>Get to this scale and you can play Lego with individual molecules. You …

Nanotechnology offers small food for thought

Imagine a humble grain of rice. Shrink it down a thousand times, and it becomes the size of a human skin cell. Shrink it a thousand times more, and you arrive at the nanoscale, where matter is measured in billionths of a metre.<p>Over the past three decades, scientists have developed a plethora of …

Nanotechnology in food: more than a question of taste

<b>Tim Lang:</b> 'Do you really want to eat these ingredients?'<p>I am troubled by the rise of nanotechnology in the food industry. It's being developed far in advance of public awareness. We've been here before: additives, irradiation, and genetic modification were all fixes promoted by industry which came …

Mapping the mind with nanotechnology

In April this year President Obama announced a hugely ambitious science project, the "Brain" Initiative (Brain Research through Advancing Innovative Neurotechnologies). Obama was giving his support, and the promise of hard cash – $100m (£65m) in 2014 and up to billions of dollars in total – to a …

Nanotechnology and religion: a complex relationship

In the science fiction short story Halo, a panel of Muslim scholars discuss a strip of bacon made by a "molecular assembler", a device capable of producing the meat directly from individual atoms, instead of slicing it from an animal. All meat from a pig is forbidden according to Islam's halal …

Nanotechnology Printer On The Horizon

Desktop printers are advancing in revolutionary ways, from 3-D printers that could in principle help manufacture robots at home to cell-placing …

Is nanotechnology safe? | Kostas Kostarelos

A nanomaterial that is 'unsafe' from an environmental standpoint may be a safe, essential tool for oncologists or neurosurgeons<p>I have a confession to make. I never thought, when I started our laboratory in 1998 at the medical school of Cornell University in New York, that I would ever be concerned …

Nanotechnology on the crime scene

Imagine a crime scene: a person in a pool of blood, and a sheet of paper with a confused message, with overlapped sentences that appear to have been written by more than one hand. Some of the things forensic experts would do today are detecting fingerprints around the room, collecting samples of …

Small is beautiful – nanotechnology in pictures

Photograph: Shruti Gour/Drexel University<p>Spray drying is a commonly used technique in the pharmaceutical industry to control the particle size and distribution of powders. It typically results in shrunken and partly collapsed particles. This is due to the initial formation of a dry shell around a …

How nanotechnology could revolutionise food storage

Nanotech can help to prevent food wastage – and solve Lady Gaga's wardrobe problems<p>I'm sure you were thinking the same thing I was when Lady Gaga made her appearance at the 2010 MTV Music Video Awards – beautiful dress, but how is she going to store it? Nanotechnology could have a solution for …

How nanotechnology can trick the body into accepting fake bones

Altering the surface of orthopaedic implants has already helped patients – and nanotech can fight infections too<p>One of medicine's primary objectives is to trick the body into doing something it doesn't want to do. We try to convince our immune systems to attack cancer cells (our immune systems …
