The Gracias‘ microgripper video is now on Metacafe for those that have never seen it. The video shows a microgripper sliding down a test tube and grabbing a sample of cow tissue. The device is thermally triggered to close, and is magnetically driven. The video is shown below, there is no sound.

Tetherless Microgrippers Grabs Tissue Sample

Link to paper for those interested: Tetherless thermobiochemically actuated microgrippers

A digested version of this research was written up by Lewis Brindley for the RSC Chemistry World: Micro-machines get a grip
