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: Can we see monkeys from space? Emerging technologies to map biodiversity

An international team of scientists has proposed a new multi-disciplinary approach in which an array of new technologies will allow us to map biodiversity and the risks that wildlife is facing at the scale of whole landscapes. The findings are published in Nature Ecology and Evolution. This international research is led by the Kunming Institute of Zoology from China, University of East Anglia, University of Leicester and the Leibniz Institute for Zoo and Wildlife Research.

Using a combination of satellite and ground data, the team proposes that it is now possible to map biodiversity with an accuracy that has not been previously...

Im Focus: Climate satellite: Tracking methane with robust laser technology

Heatwaves in the Arctic, longer periods of vegetation in Europe, severe floods in West Africa – starting in 2021, scientists want to explore the emissions of the greenhouse gas methane with the German-French satellite MERLIN. This is made possible by a new robust laser system of the Fraunhofer Institute for Laser Technology ILT in Aachen, which achieves unprecedented measurement accuracy.

Methane is primarily the result of the decomposition of organic matter. The gas has a 25 times greater warming potential than carbon dioxide, but is not as...

Im Focus: How protons move through a fuel cell

Hydrogen is regarded as the energy source of the future: It is produced with solar power and can be used to generate heat and electricity in fuel cells. Empa researchers have now succeeded in decoding the movement of hydrogen ions in crystals – a key step towards more efficient energy conversion in the hydrogen industry of tomorrow.

As charge carriers, electrons and ions play the leading role in electrochemical energy storage devices and converters such as batteries and fuel cells. Proton...

Im Focus: A unique data centre for cosmological simulations

Scientists from the Excellence Cluster Universe at the Ludwig-Maximilians-Universität Munich have establised "Cosmowebportal", a unique data centre for cosmological simulations located at the Leibniz Supercomputing Centre (LRZ) of the Bavarian Academy of Sciences. The complete results of a series of large hydrodynamical cosmological simulations are available, with data volumes typically exceeding several hundred terabytes. Scientists worldwide can interactively explore these complex simulations via a web interface and directly access the results.

With current telescopes, scientists can observe our Universe’s galaxies and galaxy clusters and their distribution along an invisible cosmic web. From the...
