(Phys.org)—A microscale technique known as optical trapping uses beams of light as tweezers to hold and manipulate tiny particles. Stanford researchers have found a new way to trap particles smaller than 10 nanometers - and potentially down to just a few atoms in size – which until now have escaped light's grasp.
