The discovery and development of optical tweezers won the 2018 Nobel Prize in physics. Now physicists are using this tool to crack some of the fundamental questions behind how the universe works.
Using lasers to trap and move particles changed the way we’re able to study microscopic life.
The Nobel Prize for physics was awarded to three scientists for the inventions of optical tweezers – in which two laser beams can hold a tiny object – and a method for creating powerful lasers.
