The laureates’ work has allowed scientists to capitalize on some of the properties of the nanoworld, and quantum dots are now found in living rooms and operating theaters across the world.

They are now widely used in TVs and have several advantages over traditional LCD panels, creating more vibrant and accurate colors, as well as requiring less energy to operate.

The dots are also widely used in medical diagnostics. Doctors use them to illuminate molecules that can bind themselves to cancer tumors, allowing the surgeon to distinguish the healthy tissue from the diseased.

The Nobel committee explained how the scientists’ work had helped develop quantum dots.

In the 1980s, Ekimov created size-dependent quantum effects in colored glass. “The color came from nanoparticles of copper chloride and Ekimov demonstrated that the particle size affected the color of the glass via quantum effects,” the committee said.

A few years later, Brus became the first scientist to prove size-dependent quantum effects in particles floating freely in a liquid.

In 1993, Bawendi then changed the chemical production of quantum dots, resulting in what the committee called “almost perfect particles.” This development allowed the dots to be used in applications.

Bawendi, a professor at the Massachusetts Institute of Technology, and Brus, professor emeritus at Columbia University, are American. Ekimov is Russian and works for Nanocrystals Technology Inc.
