robotic tweezers
Scientists have developed a pair of robotic hands that are both strong and sensitive. The tweezers can guide themselves to pick up and move individual cells without damaging them, and have a grip that can be as slight as 20 nanoNewtons of force. In fact, so advanced are the little grippers, that they can be hitched up to a microscope and, with the right software, function without human control. More below.
