   Abstract : 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.

4. 12. Synthesis of degradable aliphatic polyesters: strategies to tailor the polymer microstructure

   Author : Jenny Fagerland; Anna Finne-Wistrand; David Kaplan; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Polymer synthesis; enzymatic synthesis; degradable polyesters; peptides; scaffolds; Chemical Engineering; Kemiteknik;

   Abstract : Key factors for successful tissue engineering are the synthesis and design of the scaffold materials. Aliphatic polyesters have been studied and often used as scaffold materials for tissue engineering. However, their lack of biological cues and degradation under high-temperature processing (e.g. READ MORE

5. 13. Macromolecular synthesis of functional degradable aliphatic polyesters and porous scaffold design

   Keywords : NATURVETENSKAP; NATURAL SCIENCES; functional polyesters; condensation polymerization; L-lactide; ε-caprolactone; triblock copolymer; mechanical properties; porous scaffolds; tissue engineering; ring-opening polymerization; Bi III acetate; creatinine; stannous 2-ethylhexanoate; enzyme; degradation products; Polymer chemistry; Polymerkemi;

   Abstract : There is an increasing demand for new materials in biomedical applications with material properties that are highly specific for each application area. The search for new materials requires the creation of materials with suitable mechanical properties, functionalities, three-dimensional structures and a controlled degradation profile. READ MORE

6. 14. Polyesters with indole as sustainable aromatic component

   Author : Ping Wang; Centrum för analys och syntes; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; indole; sustainable polyesters; high performance; recycling; biodegradation;

   Abstract : Plastics are widely used in our daily lives and industry. Unfortunaltely, most plastics are produced from non-renewable fossil resources. The transition toward sustainable resources such as various biomass is critically important for the future of plastic industry and the whole society. READ MORE

7. 15. Aliphatic Polyesters for Soft Tissue Engineering : Development from Conventional Organometallic to Novel Enzymatic Catalysis

   Author : Rajiv Kumar Srivastava; Ann-Christine Albertsson; Stanishaw Penzzek; KTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; aliphatic polyester; 1; 5-dioxepan-2-one; ε-caprolactone; L-lactide; D-lactide; D; L-lactide; enzyme; lipase CA; lipase PS; Polymer chemistry; Polymerkemi;

   Abstract : The development of macromolecules with defined structure and properties, aimed specifically for biomedical applications, has resulted in diverse biodegradable polymers with advanced architectures. Among them, aliphatic polyesters synthesized by ring-opening polymerization (ROP) of lactones and lactides have a leading position due to their good mechanical properties, hydrolyzability and biocompatibility.
