Moungi G. Bawendi, Louis E. Brus and Alexei I. Ekimov “for the discovery and synthesis of quantum dots”. The Nobel Prize in Chemistry 2023 rewards the discovery and development of quantum dots, nanoparticles so tiny that their size determines their properties. These smallest components of nanotechnology now spread their light from televisions and LED lamps, and can also guide surgeons when they remove tumour tissue, among many other things. The Nobel Prize amount for 2023 is set at Swedish kronor (SEK) 11.0 million per full Nobel Prize.
Everyone who studies chemistry learns that an element’s properties are governed by how many electrons it has. However, when matter shrinks to nano-dimensions quantum phenomena arise; these are governed by the size of the matter. The Nobel Laureates in Chemistry 2023 have succeeded in producing particles so small that their properties are determined by quantum phenomena. The particles, which are called quantum dots, are now of great importance in nanotechnology.
Quantum dots now illuminate computer monitors and television screens based on QLED technology. They also add nuance to the light of some LED lamps, and biochemists and doctors use them to map biological tissue.
Quantum dots are thus bringing the greatest benefit to humankind. Researchers believe that in the future they could contribute to flexible electronics, tiny sensors, thinner solar cells and encrypted quantum communication – so we have just started exploring the potential of these tiny particles.

The Nobel Prize in Chemistry has been awarded 114 times to 191 Nobel Prize laureates between 1901 and 2022. Frederick Sanger and Barry Sharpless have both been awarded the Nobel Prize in Chemistry twice. This means that a total of 189 individuals have received the Nobel Prize in Chemistry.

The Nobel Prize medal in chemistry was designed by Swedish sculptor and engraver Erik Lindberg and represents Nature in the form of a goddess resembling Isis, emerging from the clouds and holding in her arms a cornucopia. The veil which covers her cold and austere face is held up by the Genius of Science.
To date, the youngest Nobel Prize laureate in chemistry is Frédéric Joliot, who was 35 years old when he was awarded the chemistry prize in 1935, together with his wife, Irène Joliot-Curie.
The oldest Nobel Prize laureate in chemistry to date is John B. Goodenough, who was 97 years old when he was awarded the chemistry prize in 2019. He is also the oldest laureate to be awarded in all prize categories.
