      Front Cover: Solvent-annealing-induced nanowetting in templates (SAINT) is developed to fabricate tailored polystyrene (PS) and poly(methyl methacrylate) (PMMA) nanostructures. When the swollen polymers are in the partial wetting regime, polymers wet the nanopores by capillary action, resulting in the formation of polymer nanorods. When the swollen polymers are in the complete wetting regime, polymers form wetting layers in the nanopores, resulting in the formation of polymer nanotubes. Further details can be found in the article by J.-T. Chen,* C.-W. Lee, M.-H. Chi, and I.-C. Yao on page 348.

      This Review provides the reader with a state-of-the-art overview of the crosslinking chemistries that have been used in the area of self-healing polymer materials. They have been categorized as extrinsic or intrinsic materials based upon the nature of the healing mechanism.

    1. Light-Triggered Multifunctionality at Surfaces Mediated by Photolabile Protecting Groups (pages 310–329)

      Jiaxi Cui, Verónica San Miguel and Aranzazu del Campo

      Article first published online: 7 DEC 2012 | DOI: 10.1002/marc.201200634

      Thumbnail image of graphical abstract

      Photoremovable protecting groups can be applied to thin polymer films and hydrogels to achieve light-mediated remote control of their (bio)chemical and physical properties. Spatial, temporal and compositional control of the light-induced changes is possible. By using chromophores with selective sensitivity to different wavelengths, multiple functional states can be generated. This strategy offers interesting possibilities for the next generation of instructive materials for cell culture and tissue regeneration.

    1. Nematic Liquid Crystalline Elastomer Grating and Microwire Fabricated by Micro-Molding in Capillaries (pages 330–334)

      Renbo Wei, Yaning He, Xiaogong Wang and Patrick Keller

      Article first published online: 20 DEC 2012 | DOI: 10.1002/marc.201200667

      Thumbnail image of graphical abstract

      A new approach is developed to fabricate highly oriented mono-domain nano/microstructures of liquid crystalline elastomer through micro-molding in capillaries. By filling the channels with a nematic monomer mixture and photo-crosslinking, gratings with precisely controlled sizes are fabricated. Microwires are obtained by peeling off the structure from the substrate and reversible thermomechanical deformation is observed for the microwires.

    2. Preparation of Reactive Three-Dimensional Microstructures via Direct Laser Writing and Thiol-ene Chemistry (pages 335–340)

      Alexander S. Quick, Joachim Fischer, Benjamin Richter, Thomas Pauloehrl, Vanessa Trouillet, Martin Wegener and Christopher Barner-Kowollik

      Article first published online: 23 JAN 2013 | DOI: 10.1002/marc.201200796

      Thumbnail image of graphical abstract

      Reactive 3D microstructures are fabricated by two-photon direct laser writing of a tetra-functional thiol with a tetra-functional allyl ether via radical thiol-ene polymerization, expressing residual thiol functionalities on the surface of the structure. These functionalities can be readily addressed by thiol-Michael addition reactions, evidenced by fluorescence microscopy and X-ray photoelectron spectroscopy.

    3. Photo-Degradable, Protein–Polyelectrolyte Complex-Coated, Mesoporous Silica Nanoparticles for Controlled Co-Release of Protein and Model Drugs (pages 341–347)

      Xuejuan Wan, Tao Liu, Jinming Hu and Shiyong Liu

      Article first published online: 6 DEC 2012 | DOI: 10.1002/marc.201200673

      Thumbnail image of graphical abstract

      Decomposable protein–polyelectrolyte complexes (PPCs) formed by the protein bovine serum albumin (BSA) and charge reversible polymers are utilized as a novel strategy towards the on/off switching of nanopore entrances on mesoporous silica nanoparticles (MSNs). Under photo-irradiation, disruption of the PPC coating on MSNs can lead to the co-release of BSA and loaded rhodamine B.

    4. Solvent-Annealing-Induced Nanowetting in Templates: Towards Tailored Polymer Nanostructures (pages 348–354)

    5. Organic Nonvolatile Resistive Switching Memory Based on Molecularly Entrapped Fullerene Derivative within a Diblock Copolymer Nanostructure (pages 355–361)

      Article first published online: 27 DEC 2012 | DOI: 10.1002/marc.201200614

      Thumbnail image of graphical abstract

      Flexible nonvolatile resistive memory devices using self-assembled block copolymer/PCBM nanocomposites are introduced. The spherical phase of PS10-b-PMMA130 finely controls the segregation of PCBM and improves the performance of memory devices. The memory devices show bipolar characteristics with stable and reproducible performance.

    6. Facile Synthesis of Multicompartment Micelles Based on Biocompatible Poly(3-hydroxyalkanoate) (pages 362–368)

      Julien Babinot, Estelle Renard, Benjamin Le Droumaguet, Jean-Michel Guigner, Simona Mura, Julien Nicolas, Patrick Couvreur and Valérie Langlois

      Article first published online: 12 DEC 2012 | DOI: 10.1002/marc.201200692

      Thumbnail image of graphical abstract

      A simple and straightforward method to produce poly(3-hydroxyalkanoate)-based (PHA) multicompartment micelles is presented. Thiol-ene addition is used to efficiently synthesize perfluorooctyl and poly(ethylene glycol)-grafted PHA. These copolymers are shown to self-assemble into multicompartment micelles upon nanoprecipitation in water by cryo-transmission electron microscopy. Moreover, their in vitro cytocompatibility is investigated.
