  1. The Fluid Joint: The Soft Spot of Micro- and Nanosystems

    Massimo Mastrangeli

    Article first published online: 30 JUN 2015 | DOI: 10.1002/adma.201501260

    The physical properties of fluid bridges and joints and their main applications in micro- and nanosystems engineering are reviewed. Assembly, manipulation, actuation, and particle dispensing are surveyed, all benefitting from the specific features of such ubiquitous and deceptively simple objects. The present fundamental and technological issues, as well as future research perspectives are outlined.

  2. Observing Atoms at Work by Controlling Beam–Sample Interactions

    Low-dose-rate in-line electron holography utilizes less than 100 e Å−2 s−1 to capture noise-dominated electron microscopy images that are reconstructed to produce structure images of genuine nanomaterials and surfaces. Radiation-sensitive mate­rials such as composites or catalysts can now be imaged at truly atomic resolution while minimizing electron-beam-induced structure alterations.

  3. Localized Neuron Stimulation with Organic Electrochemical Transistors on Delaminating Depth Probes

    Adam Williamson, Marc Ferro, Pierre Leleux, Esma Ismailova, Attila Kaszas, Thomas Doublet, Pascale Quilichini, Jonathan Rivnay, Balázs Rózsa, Gergely Katona, Christophe Bernard and George G. Malliaras

    Article first published online: 30 JUN 2015 | DOI: 10.1002/adma.201500218

    Organic electrochemical transistors are integrated on depth probes to achieve localized electrical stimulation of neurons. The probes feature a mechanical delamination process which leaves only a 4 μm thick film with embedded transistors inside the brain. This considerably reduces probe invasiveness and correspondingly improves future brain-machine interfaces.

  4. Magnetic-Induced Luminescence from Flexible Composite Laminates by Coupling Magnetic Field to Piezophotonic Effect

    Man-Chung Wong, Li Chen, Ming-Kiu Tsang, Yang Zhang and Jianhua Hao

    Article first published online: 30 JUN 2015 | DOI: 10.1002/adma.201502015

    Magnetic-induced luminescence (MIL) is realized via a strain mediated coupling strategy. MIL composite laminates composed of magnetic actuator and phosphor phases are developed. The MIL performance is tested under low magnetic fields at room temperature. Our results provide a novel type of promising luminescent and magnetic materials for developing some new concept devices.

  5. 3D-Printed Artificial Microfish

    Wei Zhu, Jinxing Li, Yew J. Leong, Isaac Rozen, Xin Qu, Renfeng Dong, Zhiguang Wu, Wei Gao, Peter H. Chung, Joseph Wang and Shaochen Chen

    Article first published online: 29 JUN 2015 | DOI: 10.1002/adma.201501372

    Hydrogel microfish featuring biomimetic structures, locomotive capabilities, and functionalized nanoparticles are engineered using a rapid 3D printing platform: microscale continuous ­optical printing (μCOP). The 3D-printed ­microfish exhibit chemically powered and magnetically guided propulsion, as well as highly efficient detoxification capabilities that highlight the technical versatility of this platform for engineering advanced functional microswimmers for diverse biomedical applications.
