About Nanoco Group plc

Nanoco (LSE: NANO) is a nano-material production and licensing company, specialising in the production of its patented cadmium free quantum dots (CFQD®) and other patented nano-materials for use in the electronics industries.

Founded in 2001 and headquartered in Runcorn, UK, Nanoco continues to build out a world-class, patent-protected IP portfolio alongside the scaling of the production for commercial orders.

Nano-materials are materials with dimensions typically in the range 1 - 100 nm. Nano-materials have a range of useful properties, including optical and electronic. Quantum dots are a subclass of nano-material that have size-dependent optical and electronic properties. Within the sphere of quantum dots, the Group exploits different characteristics of the quantum dots to target different performance criteria that are attractive to specific markets or end-user applications such as the Sensor, Electronics and Display markets. Nanoco's CFQD® quantum dots are free of cadmium and other toxic heavy metals, and can be tuned to emit light at different wavelengths across the visible and infrared spectrum, rendering them useful for a wide range of display applications. Nanoco's HEATWAVE? quantum dots can be tuned to absorb light at different wavelengths across the near-infrared spectrum, rendering them useful for applications including cameras and image sensors.

Nanoco is listed on the Main Market of the London Stock Exchange, holds the LSE's Green Economy Mark, and trades under the ticker symbol NANO. For further information please visit: www.nanocotechnologies.com
