    Sammanfattning : Advancements in drug delivery have enabled a wider array of prevention, control and treatment of diseases such as cancer. Drug delivery systems have the possibility of encapsulating drugs with low solubility, delivering them to specific locations in the body as well as obtaining a controlled and sustained drug release.

  3. 2. Polyester scaffold: Material design and cell-protein-material interaction

    Författare :Staffan Dånmark; Anna Finne-Wistrand; Ann-Christine Albertsson; Kamal Mustafa; Pentti Tengvall; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Tissue engineering has emerged as a valid approach for the regeneration and restoration of bone defects. The concept of bone tissue engineering includes degradable scaffolds, osteogenic cells and osteoinductive growth factors either alone or in any combination of these three. LÄS MER

  4. 3. Exploring the Use of Terpenes as Renewable Polymer Feedstock

    Författare :Arne Stamm; Per-Olof Syrén; Nico Bruns; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Bio-based polymers; terpenes; α-pinene; sobrerol methacrylate SobMA ; verbanone lactone VaL ; 1- 1 -hydroxyethyl -3- 2 -hydroxyethyl -2; 2- dimethylcyclobutane HHDC .; Kemi; Chemistry;

    Sammanfattning : Rising environmental awareness and responsibility has increased the demand for novel,  bio-based  sustainable  materials.  Therefore,  there  is  an  extensive  need  to research  and  develop  closed-loop  materials  from  novel  feedstocks  that  can  be generated  using  benign,  environmentally  friendly  synthetic  routes.

  5. 4. Exploring bio-based and biodegradable polymers: free-radical polymerization, hydrolysis and applications

    Författare :Maryam Mousa; Eva Malmström; Magnus Jonsson; Anna Larsson Kron; Seema Agarwal; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Bio-based polymers; biodegradation; branched polyesters; thermally expandable microspheres; copolymerization; Fiber- och polymervetenskap; Fibre and Polymer Science;

    Sammanfattning : Increasing concerns regarding the depletion of fossil-based resources and theaccumulation of plastic waste in the environment have resulted in extensiveresearch aimed at finding more sustainable alternatives to today’s plastics.In this work, bio-based and biodegradable polymers have been synthesizedusing free-radical polymerization in homogeneous and heterogeneoussystems.

  7. 5. Large scale synthesis of polyesters with low amount of residual tin

    Författare :Anna Stjerndahl; Ann-Christine Albertsson; Johan Lind; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Polymer chemistry; Polymerkemi;

    Sammanfattning : Användningen av resorberbara polymerer för applikationer inom vävnadsersättning har ökat markant under de senaste decennierna. Tekniken innebär att celler får växa på ett polymert bärarmaterial och på så sätt återskapa skadad vävnad, och är ett lovande alternativ till många av de implantat som används idag. LÄS MER
