New tweezers can reach smaller particles and keep their cool
Scientists have been working on ways for decades to trap tiny microscopic parts of a cell. Today, scientists are going even further with the ability to trap even smaller nanoscale particles using optical tweezers. The original optical tweezers used on microscopic particles had issues with overheating that made them impractical for use with smaller nanoscale particles.Engineers at Harvard have been able to create a device that makes it easier to isolate nanoparticles like viruses and tiny individual cellular components. The optical tweezers use light from a laser to trap particles....
