World's Tiniest Tweezers Grab Nanoparticles Using Nothing But Light

When you're working with tiny nanoparticles, you need extremely delicate tools. Like, say, tweezers that can manipulate particles 1,000 times thinner than a human hair without physically touching them. That's exactly what researchers at the Institute of Photonic Sciences have come up with: optical nanotweezers that… » 3/04/14 3:40pm 3/04/14 3:40pm
