  1. Glycopolymer Polyelectrolyte Multilayers Composed of Heparin and Maltose-Modified Poly(ethylene imine) as a Strong/Weak Polyelectrolyte System for Future Drug Delivery Coatings: Influence of pH and Sugar Architecture on Growth of Multilayers and Multilayer Swelling and Stability

    Biocompatible branched and linear sugar architectures, cationic dendritic ­glycopolymer, and anionic heparin are used to fabricate polyelectrolyte multilayers (PEMs) by the layer-by-layer method. The physiological stability of PEMs, tailored by pH-dependent polyelectrolyte deposition on the PEM surface, is needed for future PEM use in biomedical applications (e.g., sensors or drug-delivery systems).

  2. pH-Sensitive Drug-Conjugates on Water-Soluble Polymer Frameworks

    Abu Bakkar Siddique, Youngjun Cho, Yujin Kim, Sung Hoon Bahng, Sung Woo Kim, Jae Yeol Lee, Ho-Jung Kang, Sehoon Kim, You Han Bae and Jungahn Kim

    A potent synthetic methodology to generate a useful intermediate for the preparation of pH-sensitive polymeric pro-drugs by a combination of living anionic block polymerization of ethylene oxide (EO) and N-phenylmaleimide (N-PMI) and the Gabriel process is introduced. Hydrazinolysis of the resulting poly(ethylene oxide)-block-poly(N-PMI) (PEO-b-PN-PMI) using hydrazine under acidic conditions leads to the production of the corresponding PEO-based frameworks with hydrazide (HZ) groups. The HZ groups are found to effect the formation of the acid-sensitive bond under neutral conditions (pH = 7.2).

  3. Bioinspired Polymeric Nanocomposites for Regenerative Medicine

    Designing bioinspired nanomaterials for tissue-engineering applications requires a fundamental understanding of the interactions between polymers, nanostructures, and cells. Biomimetic structures composed of fibrous architectures are discussed, the emerging trends in designing complex nanocomposites with multiple functionalities are assessed and finally, some of the most critical challenges that come with the design and fabrication of bioinspired polymeric nanocomposites are highlighted.

  4. Dynamic Response of Anchored Poly(N-isopropylacrylamide-co-methacrylic acid-co-benzophenone methacrylate) Terpolymer Hydrogel Layers to Physicochemical Stimuli

    Maria Gianneli, Ilke Anac, Robert Rostkamp, Bernhard Menges, Benoit Loppinet, Uli Jonas, Wolfgang Knoll and George Fytas

    Article first published online: 18 NOV 2014 | DOI: 10.1002/macp.201400361

    The structure and dynamics in photo-crosslinked, surface-attached films (≈1 μm dry thickness) of a poly(N-isopropylacryl­amide) (PNIPAAm)-based terpolymer at different temperature and salt contents are reported. The dynamics respond distinctly to structural changes induced by increasing temperature or added salt.
