[Philip Lelyveld comment: Nanoco is mass producing quantum dots, using no heavy metals, for manufacturers in the UK and Japan.]

[from Nanoco website]

Nanoco Group PLC and its operating subsidiary Nanoco Technologies Ltd partner major R&D and blue-chip industrial organisations in the development of applications incorporating semiconductor nanoparticles, “quantum dots”.

Nanoco Technologies is unique in the nanomaterials market as a company that manufacture large quantities of quantum dots. Our molecular seeding process for the bespoke manufacture of these nanoparticles on a commercial scale is protected by worldwide patents.

Nanoco Technologies is the only manufacturer currently able to supply production quantities of these nanoparticles which do not use a regulated heavy metal. We are the only manufacturer able to respond to orders for large quantities of bespoke quantum dots, and we are leading the way in customising the functionalisation of quantum dots enabling chemical linkage for biological and other specific uses.

The bulk manufacture of quantum dots provides our partners with the platform to develop a wide variety of next-generation products, particularly in application areas such as display technology, lighting, solar cells and biological imaging.

Nanoco Technologies’ research and manufacturing headquarters was established in Manchester (UK) in 2001. The company currently operates facilities in the UK and Japan.
