    A cholesterol-based dendritic amphiphile forms highly charged and stable monolayers at the air–liquid interface offering exquisite control over calcium phosphate mineralization.

  2. Enhanced Self-Renewal and Accelerated Differentiation of Human Fetal Neural Stem Cells Using Graphene Oxide Nanoparticles

    The application of graphene oxide (GO) nanoparticles (GO-NPs) to engineer self-renewal and differentiation of human fetal neural stem cells (hfNSCs) is reported. Incorporation of GO-NPs into hfNSC neurospheres significantly promotes cell-to-cell and cell-to-matrix interactions, leading to enhanced self-renewal ability and accelerated differentiation of hfNSCs. Thus, GO-NPs can be proposed as a promising nanobiomaterial to engineer stem cell therapeutics for neuronal tissue regeneration.

  3. Synthesis and Validation of Functional Nanogels as pH-Sensors in the Hair Follicle

    Mathias Dimde, Fitsum Feleke Sahle, Virginia Wycisk, Dirk Steinhilber, Luis Cuellar Camacho, Kai Licha, Jürgen Lademann and Rainer Haag

    Nanosensors for the pH measurement inside the hair follicle (HF) are described. Dye-labeled dendritic polyglycerol based nanogels (dPG-NG) are used to penetrate inside the HF and measure the pH values using an ex vivo porcine ear model. The dPG-NGs are synthesized with a mild and surfactant-free Thiol–Michael reaction using an inverse nanoprecipitation method and can be fine-tuned to particle sizes of 100 nm to 1 µm.

  4. Immobilization of Enzymes on PLGA Sub-Micrometer Particles by Crosslinked Layer-by-Layer Deposition

    Sandro Sieber, Stefan Siegrist, Stéphanie Schwarz, Fabiola Porta, Susanne H. Schenk and Jörg Huwyler

    Enzyme immobilization on poly(lactide-co-glycolide) (PLGA) particles via crosslinked layer-by-layer deposition. Model enzymes (brown) are immobilized on sub-micrometer PLGA particles (green) by a combined approach based on electrostatic adsorption and covalent crosslinking according to the layer-by-layer principle. Two opposite charged polyelectrolytes, poly(allylamine hydrochloride) (red) and poly(styrene sulfonate) (blue), are combined with the crosslinking agent glutaraldehyde.

  5. Poly (Ethylene Glycol)-Based Hydrogels as Self-Inflating Tissue Expanders with Tunable Mechanical and Swelling Properties

    Mahsa Jamadi, Parvin Shokrollahi, Behzad Houshmand, Mortaza Daliri Joupari, Fatemeh Mashhadiabbas, Ali Khademhosseini and Nasim Annabi

    Version of Record online: 6 APR 2017 | DOI: 10.1002/mabi.201600479

    Self-inflating expanding hydrogels based on poly (ethylene glycol) diacrylate (PEGDA) polymers with different molecular weights are developed, resulting in mechanically tunable and resilient tissue expanders. In vitro and in vivo swelling ratio and mechanical properties, in addition to their enough pressure to expand soft tissue, make these PEGDA-based hydrogel formulations suitable candidates for engineering a variety of tissue expanders.
