  1. Salting-Out Waterborne Catiomeric Polyurethanes for Drugs Encapsulation and Delivery

    Borja Fernández-d'Arlas and Arantxa Eceiza

    Article first published online: 3 SEP 2015 | DOI: 10.1002/macp.201500202

    High urethane density catiomeric polyurethanes self-assemble into micelles of difference sizes. The higher the fraction of hydrophobic segments the smaller the micelles. After incubation with model drugs (MDs) such as fluorescein and a salting-out process with a high ionic strength kosmotropic media, the MDs are encapsulated into rearranged polyurethane micelles.

  2. A Biodegradable Coating Based on Self-Assembled Hybrid Nanoparticles to Control the Performance of Magnesium

    Jiadi Sun, Ye Zhu, Long Meng, Tiantian Shi, Xiaoya Liu and Yufeng Zheng

    Photoresponsive self-assembled hybrid nanoparticles are electrodeposited onto a Mg sample. The nanoparticle modified Mg surfaces have an advantage in corrosion resistance and cell survival. These new coating layers may be used as surface materials to control the performance of Mg-based implants.

  3. A Redox-Responsive Supramolecular Hydrogel for Controllable Dye Release

    Wei Ji, Guo Feng Liu, Ming Xin Xu and Chuan Liang Feng

    Article first published online: 3 SEP 2015 | DOI: 10.1002/macp.201500210

    Redox-responsive supramolecular hydrogels coassembled from small organic molecules are constructed using a novel and easy approach. The ability of the nanofibrous hydrogel to encapsulate a controllable-release model drug under the reductive condition mimicking the intracellular environment is demonstrated. The results suggest the redox-responsive coassembled hydrogel holds great promise as a drug carrier for controllable drug release in nanomedicine and cancer therapy.

  4. Controlled Synthesis of Well-Defined Semiconducting Brush Polymers

    Dean van As, Jegadesan Subbiah, David J. Jones and Wallace W. H. Wong

    Well-defined polythiophene-based bottlebrush polymers are prepared using controlled polymerization methods. The bottlebrush polymers are characterized and compared with linear poly(3-hexylthiophene). It is found that longer polythiophene chains impart better semiconducting properties, resulting in higher solar-cell device performance.

  5. Thermally Induced Crosslinking of Poly(N-Propargyl Glycine)

    Christian Secker, Sarah M. Brosnan, Felix R. P. Limberg, Ulrike Braun, Matthias Trunk, Peter Strauch and Helmut Schlaad

    Article first published online: 2 SEP 2015 | DOI: 10.1002/macp.201500223

    Poly(N-propargyl glycine) undergoes crosslinking simply upon heating in the absence of any additives or metal catalysts. The crosslinking process is analyzed by thermal analysis (differential scanning calorimetry and thermogravimetric analysis), Fourier-transform infrared, electron paramagnetic resonance, and solid-state NMR spectroscopy.
