Trio wins chemistry prize for 'smallest machines'

Jean-Pierre Sauvage, J. Fraser Stoddart and Bernard Feringa won the Nobel chemistry prize on Wednesday for work on molecular machines that may lead to developments like new materials, sensors and energy storage systems.

"This year's Nobel Prize in Chemistry is about the world's smallest machines," said Goran Hansson, a member of the Royal Swedish Academy of Sciences which conferred the award.

The French, Scottish and Dutch scientists had developed molecules with controllable movements that can perform tasks when energy is added, the Academy said in a statement awarding the 8 million Swedish crown ($931,000) prize.
