Scientists write with nanoparticles using a laser and a bubble
Nanoparticles are extremely small -- less than 100 nanometers in size -- but they can have a big impact on medicine, solar technology, batteries, computing and other industries. Nanoparticles are generally more reactive, stronger and more versatile than other molecules, though at just one-billionth of a meter in size, they're notoriously difficult to maneuver. But, that final barrier may disappear soon. Engineers Yuebing Zheng, Deji Akinwande and Andrew Dunn at the University of Texas' Cockrell School created a technique that allows researchers to deftly pick up individual nanoparticles and move them to specific locations. The creators call it "bubble-pen lithography."
