Quantum dots: get your free samples here!

23.10.2002


A company spun out from the UK’s University of Manchester has become the first in the world to produce and ship multi-gram quantities of quantum dots – and has launched a unique ‘Free Evaluation Samples’ program throughout the EU and UK.

Using a patented process, Nanoco Ltd is not only able to ship its standard ‘NanoDots’ in production-level quantities to meet growing market demand, but can easily configure NanoDots to meet custom performance specifications – previously a long process of trial and error.

Up to this point quantum dots - essential building blocks of multiple nanotechnological applications, from electronics to life science - have been produced in small batches of fractions of a gram in various labs around the world from a method that’s both cumbersome and hazardous.



NanoDots are particles so tiny it would take about 80,000 to span a human hair. Consequently, their characteristics are bound by the laws of quantum physics (hence ‘quantum dots’). For example, when exposed to light energy of various wave lengths, they emit energy of a different wavelength. This phenomenon can be put to a myriad of useful purposes: inks and dyes containing NanoDots can provide unique, visible light signatures to authenticate products and documents; they can be triggered by light to release very exact doses of drugs or DNA to particular parts of the human body; windows coated with NanoDots can self-clean and automatically adjust the amount of shade they provide in response to sunlight, leading to huge savings in energy costs. Indeed, the benefits are so widespread that the particles could be considered the ‘ball bearings’ of the 21st century. The US Government and the European Commission are currently pumping around a billion dollars a year into R&D that accelerates progress in nanotechnology – a market than some analysts estimate will hit $200 billion by 2006.

Nanoco has patented a unique single source precursor (‘one pot’) manufacturing production process which:

? Does not involve the highly toxic, highly inflammable and unstable materials that impose severe scaling limitations on the current standard ‘double source’ process
? Makes it easier to re-size the particles’ cores and shells, and to change capping agents, etc., thus making it much simpler to tailor NanoDots to desired optical, electro-magnetic and catalytic specifications.
? Produces reliable uniformity/stability, leading to more predictable performance per the desired specification.
? Delivers economies of scale such that applications utilizing NanoDots become significantly more economically attractive.

Nanoco founder Professor Paul O’Brien, said
"The fact that we could make production volumes of NanoDots met with some skepticism from certain nanotechnology applications developers around the world, so we decided the best way to show we`re `for real` was to offer them free evaluation samples. It`s the fastest way to gain sufficient trust as a prospective supplier/partner with the people to whom we expect to deliver commercial volumes in the future."

Im Focus: UNH scientists help provide first-ever views of elusive energy explosion

Researchers at the University of New Hampshire have captured a difficult-to-view singular event involving "magnetic reconnection"--the process by which sparse particles and energy around Earth collide producing a quick but mighty explosion--in the Earth's magnetotail, the magnetic environment that trails behind the planet.

Magnetic reconnection has remained a bit of a mystery to scientists. They know it exists and have documented the effects that the energy explosions can...

Im Focus: A Chip with Blood Vessels

Biochips have been developed at TU Wien (Vienna), on which tissue can be produced and examined. This allows supplying the tissue with different substances in a very controlled way.

Cultivating human cells in the Petri dish is not a big challenge today. Producing artificial tissue, however, permeated by fine blood vessels, is a much more...

Im Focus: Penn engineers develop ultrathin, ultralight 'nanocardboard'

When choosing materials to make something, trade-offs need to be made between a host of properties, such as thickness, stiffness and weight. Depending on the application in question, finding just the right balance is the difference between success and failure

Now, a team of Penn Engineers has demonstrated a new material they call "nanocardboard," an ultrathin equivalent of corrugated paper cardboard. A square...
