Scientist use Lasers to build uber-small structures on human hair Researchers straight out of Boston College Chemistry's lab, have developed a way to deposit a polymer at the focal point of a laser beam. Scanning of the laser beam in a certain pattern allows the laser to form 3D patterns effectively creating features that are 1000 times smaller than the diameter of a human hair. In normal-people speak, they found out how to build super-tiny structres on a piece of hair. This could possibly lead to super tiny products built into our skin, hair and/or clothes. I see the shampoo industry jumping all over this one. -via BoingBoing-  ¶ 11:46 AM
