Dotz Nano Ltd

Areas of Expertise

Dotz Nano Ltd is an exciting new venture aimed at capitalising on the technological innovation in the graphene quantum dots (GQDs) market. Its vision is to be the premier producer and supplier of high quality GQDs for use in various applications, including medical imaging, sensing, consumer electronics, energy storage, solar cells and computer storage.

Dotz Nano Ltd was incorporated in March 2014 and partnered with Rice University, Texas, US, to develop and commercialise a new and innovative technology that will change the GQD market. Invested in by several private investors, Dotz Nano Ltd has signed an R&D agreement with the Tour Lab Group at Rice University, which is one of the five leading groups in graphene R&D today, to develop various products and applications for Dotz Nano Ltd GQDs.

Research Interests
  • To provide the industry with cheaper, high quality graphene quantum dots in large quantities and make this miracle product available to all;
  • Most GQDs available today are based on bulk graphene sources which in turn are based on graphite raw materials. This makes GQDs extremely expensive, with high cost production processes manufacturing very small amounts;
  • Dotz Nano Ltd’s technological production of GQDs is based on a process developed by Rice University’s Professor James Tour, one of the 50 most influential scientists in the world today. This technology sources GQDs from cheap coal in a much cheaper and efficient production process;
  • With their characteristics, Dotz Nano Ltd’s GQDs resist ‘photobleaching’, a known and problematic trait of fluorescent spectroscopy. The low cost of the raw material will also be a benefit. High quality graphite costs $2,000 (~€1,863) a tonne, while cheaper graphite is $800 a tonne from China. Coal is $10-60 a tonne and is the cheapest raw material for producing GQDs, with the process offering a 20% production yield. All involved in this market agree that the discovery can really change the quantum dot industry.
