The 2023 Nobel Prize in Chemistry has been awarded to Moungi G. Bawendi, Louis E. Brus and Alexei I. Ekimov for the discovery and synthesis of quantum dots
The 2023 Nobel Prize in Chemistry has been awarded to Moungi G. Bawendi, Louis E. Brus and Alexei I. Ekimov for the discovery and synthesis of quantum dots, the Royal Swedish Academy of Sciences said in Stockholm.
Quantum dots have unique properties and now spread their light from television screens and LED lamps. They catalyse chemical reactions and their clear light can illuminate tumour tissue for a surgeon, the Academy said in a press release.
Researchers have primarily utilised quantum dots to create coloured light. They believe that in the future quantum dots can contribute to flexible electronics, miniscule sensors, slimmer solar cells and perhaps encrypted quantum communication.
Today quantum dots are an important part of nanotechnology’s toolbox. The 2023 NobelPrize laureates in chemistry have all been pioneers in the exploration of the nanoworld, said the Academy.
In the early 1980s, this year’s chemistry laureates Louis Brus and Alexei Ekimov succeeded in creating — independently of each other — quantum dots, which are nanoparticles so tiny that quantum effects determine their characteristics.
In 1993, chemistry laureate Moungi Bawendi revolutionised the methods for manufacturing quantum dots, making their quality extremely high — a vital prerequisite for their use in today’s nanotechnology.
“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 release added.

How do you create a Christmas tree with crochet? Take notes from crochet artist Sheena Pereira, who co-founded Goa-based Crochet Collective with crocheter Sharmila Majumdar in 2025. Their artwork takes centre stage at the Where We Gather exhibit, which is part of Festivals of Goa, an ongoing exhibition hosted by the Museum of Goa. The collective’s multi-hued, 18-foot crochet Christmas tree has been put together by 25 women from across the State. “I’ve always thought of doing an installation with crochet. So, we thought of doing something throughout the year that would culminate at the year end; something that would resonate with Christmas message — peace, hope, joy, love,” explains Sheena.
