Inspired by the hominid-type hand, in article number 1704047, Camilla Parmeggiani, Diederik S. Wiersma, and co-workers engineer a microscopic equivalent that is able to catch microscopic elements, demonstrated by a 3D representation of a four-fingered microhand closing on a blood cell. This microhand is light-powered and can be either remotely controlled by optical illumination or can act autonomously, grabbing small particles on the basis of their optical properties.
