    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Ring-opening polymerization; Stannous octoate; 2; 2’-azoisobutyronitrile; 1; 5-dioxepane-2-one; ε-caprolactone; L-lactide; Trimethylene carbonate; 2-methylene-1; 3-dioxe-5-pene; Copolymer; Porous scaffold; Porous tubular scaffold; Electron beam; Gamma irradiation; Polymer chemistry; Polymerkemi;

    Sammanfattning : The regeneration of damaged tissues or organs using porous scaffolds which act as temporary guides for the patient’s own cells, i.e. tissue engineering, is a means to overcome the shortcomings of current standard medical treatments. LÄS MER

  3. 17. Biomimetic Membranes: : Molecular Structure and Stability Studies by Vibrational Sum Frequency Spectroscopy

    Författare :Jonathan F.D. Liljeblad; Mark W. Rutland; Magnus C. Johnson; Tore Brinck; Lars Kloo; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Vibrational Sum Frequency Spectroscopy VSFS ; Langmuir monolayer; LB depositon; phospholipids; oxidation; biomimetic membranes; Surface and colloid chemistry; Yt- och kolloidkemi;

    Sammanfattning : In the research presented in this licentiate thesis the surface specific technique Vibrational Sum Frequency Spectroscopy, VSFS, combined with the Langmuir trough has been utilized to investigate Langmuir monolayers and Langmuir-Blodgett (LB) deposited mono- and bilayers of phospholipids. Their molecular structure, stability, and hydration were probed to gain additional understanding of important properties aiming at facilitating the use of such layers as model systems for biological membranes.

  4. 18. Drug Eluting Hydrogels : Design, Synthesis and Evaluation

    Författare :Lage Ahrenstedt; Deon Bezuidenhout; Michael Malkoch; University of Cape Town; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Drug delivery; PEGylation; Rapamycin; Dexamethasone; Controlled release; Hydrogels; Slow release;

    Sammanfattning : Hydrogels have successfully proved themselves useful for drug delivery applications and several delivery routes have been developed over the years. The particular interest in this work was to design, synthesise and evaluate in situ forming drug eluting hydrogels, which have the potential to ameliorate the healing of cardiovascular diseases.

  5. 19. Synthetic Pathways to Aliphatic Polyesters and Scaffold Design

    Författare :Therese Tyson; Ann-Christine Albertsson; Elisabetta Ranucci; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Polymer chemistry; Polymerkemi;

    Sammanfattning : As the field of tissue engineering progresses, a continuous development of scaffold fabrication techniques and suitable degradable materials is required to obtain scaffolds with tunable characteristics. This thesis has focused on the development of pathways to synthesize degradable aliphatic polyesters and on the design of highly porous scaffolds from this class of materials. LÄS MER

  7. 20. Multifunctional Polymer Materials: From Synthesis to Disinfection

    Författare :Haiyue Gong; Tillämpad biokemi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Molecularly imprinted polymer; Antibacterial; Ag nanoparticles; Antibiotic; Boronic acid; Polyethylenimine; Quaternary ammonium;

    Sammanfattning : Polymer materials have wide applications in many industries, such as the food, pharmacy, construction, textile, and cosmetics industries. For the past few years, polymer materials have drawn the attention of scientists and engineers as a good disinfectant due to their advanced manufacturing methods, large surface areas, good stability, and lowcost.
