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: The moiré patterns of three layers change the electronic properties of graphene

Combining an atomically thin graphene and a boron nitride layer at a slightly rotated angle changes their electrical properties. Physicists at the University of Basel have now shown for the first time the combination with a third layer can result in new material properties also in a three-layer sandwich of carbon and boron nitride. This significantly increases the number of potential synthetic materials, report the researchers in the scientific journal Nano Letters.

Last year, researchers in the US caused a big stir when they showed that rotating two stacked graphene layers by a “magical” angle of 1.1 degrees turns...
