          | Description: 
             These images show a microrobot 
            in salt water from below. In the left image, the robot's three fingers 
            are open over a 100-micron bead. In the right image, the robot is 
            grasping the bead. The microrobots are designed to manipulate single 
            cells, bacterium and other microorganisms in fluid samples. |
