Moungi Bawendi, Louis Brus and Aleksey Yekimov were awarded the Nobel Prize in Chemistry 2023 for the discovery and development of quantum dots. These tiny particles have unique properties and now spread their light from television screens and LED lamps.
Did you know the QDs can also be combined with cyclodextrin? In this application, they are used for water purification, particularly to remove metal ions from water.
Great work by André FajardoArtur Valente & colleagues
