  2. 6. Biomaterials for Promoting Self-Healing of Bone Tissue

    Author : Sonya Piskounova; Jöns Hilborn; Tim Bowden; Simon Cool; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Osseointegration; implant coating; hyaluronan hydrogel; bone morphogenetic protein-2; hydroxyapatite; bone; delivery system; injectable; mixing; radioactive labeling; Kemi med inriktning mot polymerkemi; Chemistry with specialization in Polymer Chemistry;

    Abstract : The present work addresses poor bone/implant integration and severe bone defects. In both conditions external stimuli is required for new bone to form. READ MORE

  4. 7. Insights into dynamic covalent chemistry for bioconjugation applications

    Author : Shujiang Wang; Oommen Varghese; Nicola Tirelli; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; dynamic covalent chemistry; reaction mechanism; hydrogel; bioconjugation; catalysis; Kemi med inriktning mot polymerkemi; Chemistry with specialization in Polymer Chemistry;

    Abstract : Dynamic covalent chemistry (DCC) is currently exploited in several areas of biomedical applications such as in drug discovery, sensing, molecular separation, catalysis etc. Hydrazone and oxime chemistry have several advantages, such as mild reaction conditions, selectivity, efficiency, and biocompatibility and therefore, have the potential to be for bioconjugation applications.

  6. 9. Block Copolymer Electrolytes : Polymers for Solid-State Lithium Batteries

    Author : Andreas Bergfelt; Tim Bowden; Daniel Brandell; Yoichi Tominaga; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : The use of solid polymer electrolytes (SPEs) for lithium battery devices is a rapidly growing research area. The liquid electrolytes that are used today are inflammable and harmful towards the battery components. READ MORE

  7. 10. Injectable Composite Hydrogels Based on Metal-Ligand Assembly for Biomedical Applications

    Author : Liyang Shi; Jöns Hilborn; Dmitri Ossipov; Wenxin Wang; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; injectable; hydrogel; shear-thinning; self-healing; coordination chemistry; biomedical applications;

    Abstract : This thesis presents new strategies to construct injectable hydrogels and their various biomedical applications, such as 3D printing, regenerative medicine and drug delivery. These hydrogels cross-linked by dynamic metal-ligand coordination bonds exhibit shear-thinning and self-healing properties, resulting in the unlimited time window for injection. READ MORE
