The 2023 Nobel prize in chemistry has been awarded to three scientists for the discovery and development of quantum dots — super-tiny semiconductors that can be used in LED lights and TV screens, as well as to aid doctors in the removal of cancer tissue.
"For a long time, nobody thought you could ever actually make such small particles," Johan Åqvist, the chair of the Nobel committee for chemistry, said at a news conference announcing the 2023 laureates."But this year's laureates succeeded.
The tiny size of these particles means they sit somewhere between the quantum realm and the macro world, giving them a weird jumble of semi-quantum properties. For instance, if you change a quantum dot's size by swapping out atoms, it will suddenly change color.
