Illuminating Research – A bright future ahead as Nanoco sign a distribution agreement with Sigma-Aldrich

Nanoco Technologies Ltd, Manchester, UK 18 January 2008

Nanoco Technologies and Sigma-Aldrich are looking at a bright future together with the signing of a distribution agreement and launch of a new range of products based on Nanoco’s leading edge quantum dots.

The first materials available through this collaboration form the new Lumidot™ range of seven core-shell fluorescent quantum dots . Quantum dots (QDs) are nm-sized semiconductor nanoparticles that emit bright, near-monochromatic light (luminesce) under light or electrical stimulation. Emission color can be tuned by choosing nanocrystal size, making QDs ideal luminophors for cutting-edge applications including ultra-thin displays, solid-state lighting, anti-counterfeit protection, and next-generation solar cells. Nanoco developed unique manufacturing methods for making multi-gram quantities of QDs reproducibly and with precise control of size, structure, and luminescence characteristics. The new core-shell LumidotsTM distributed by Sigma-Aldrich have luminescence colors spanning the entire visible spectrum, in addition to good stability and batch-to-batch reproducibility, essential for research into high-technology applications.

The relationship makes the most of the core skills of both companies. Nanoco is unique in the Nanomaterials market as a company that manufactures large quantities of quantum dots. Sigma-Aldrich provides an excellent distribution channel as they are uniquely positioned to deliver smaller quantities of chemicals to commercial, academic and government labs around the world.

“This partnership is great for both companies and for global research”, said Michael Edelman, CEO of Nanoco Technologies, “It brings Nanoco’s manufacturing expertise together with the excellent distribution network operated by Sigma-Aldrich. We are excited to be working with them to extend the range of nanomaterials available to the worldwide research market. We plan to expand this collaboration by offering new ranges of quantum dots later in 2008 and beyond.”

“The new LumidotsTM is an important addition to our line of nanomaterials products, providing researchers around the world reliable access to high-quality quantum dot nanocrystals. Using these materials, scientists and engineers can focus on developing applications that take advantage of the unique properties of quantum dots. This fits with the main goal of Aldrich Materials Science – we focus on materials so that our customers can focus on results,” said Dr Ilya Koltover, Product Manager, Aldrich Materials Science.

Sigma-Aldrich will distribute research quantities (less than 1 g) of the quantum dots and the Lumidot™ range will be supplied as convenient 2 mL and 10 mL solutions in toluene, available to order from the Sigma-Aldrich website.

Nanoco will continue to offer larger quantities of quantum dots to partners who move beyond research to the development of commercial QD applications.
