The design of an object transportation system exploiting the bending behavior of surface‐assembled diarylethene crystals is reported. A photoactuated smart surface based on this system can transport polystyrene beads to a desired area depending on the direction of the incident light. Two main challenges were addressed to accomplish directional motion along a surface: first, the preparation of crystals...
Die Zilien von Paramecium aurelia dienten als Vorlage für das Objekttransportsystem, das R. Nishimura, K. Uchida und Mitarbeiter in ihrer Zuschrift auf S. 13442 beschreiben. Anordnungen nadelförmiger Kristalle eines photochromen Diarylethenderivats biegen sich vom einfallenden UV‐Licht weg. Durch Steuerung der Richtung des einfallenden UV‐Lichts kann so die Bewegung einer Polystyrolperle auf einer...
