Because of their nano size, the characteristics of nanoparticles are dependent on their dimensions. Nanoparticles are now used in everything from TVs and LED lights to illuminating surgical procedures like the removal of tumour tissue.

The winners were announced in Stockholm by Swedish scientist Hans Ellegren and Johan Qvist, head of the Nobel committee for chemistry at the Swedish Academy.
The declaration is included in Alfred Nobel’s testament, which lists Chemistry as a principal field.
According to a statement made by the Nobel Committee on platform X, “The 2023 Nobel Prize in Chemistry rewards the discovery and development of quantum dots, nanoparticles so tiny that their size determines their properties”.

Due to their special qualities, these particles are now widely dispersed by electronic devices such as TVs and LED lights. The researchers accelerated chemical processes, and their bright light can help a surgeon see tumour tissue.

Meanwhile, it must be mentioned that Carolyn Bertozzi, Morten Meldal, and K. Barry Sharpless shared the Nobel Prize in Chemistry in 2022 for their contributions to the fields of click chemistry and bioorthogonal chemistry. As a result of their efforts, chemistry has improved tremendously, illustrating the revolutionary potential of scientific discovery.
For their “experimental methods that generate attosecond pulses of light for the study of electron dynamics in matter,” Ferenc Krausz, Pierre Agostini, and Anne L’Huillier were awarded the Nobel Prize in Physics, which had been announced earlier by the Royal Swedish Academy of Sciences.
In the medical field, Katalin Kariko and Drew Weissman were recognised for their ground-breaking research on mRNA vaccines. These vaccinations have been very useful in the fight against Covid-19.
