    Abstract : The transition to a more biobased society introduces both new opportunities and new challenges as we replace nonrenewable materials with renewable alternatives. One important challenge will be to control microbial growth on materials, both to protect the materials from biological degradation and to prevent the spread of infections and toxins that can cause illness.

  5. 3. On Mechanisms Impairing Airway Host Defence in Cystic Fibrosis

    Author : Sandra Jovic; allergologi och palliativ medicin Lungmedicin; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Abstract : Cystic fibrosis is an inherited disease, caused by mutations of the cystic fibrosis transmembrane conductance regulator gene. The gene codes for a protein that serve as chloride channel. In cystic fibrosis, this protein is lacking or has a defect function resulting in a thick and sticky mucus of the airways. READ MORE

  6. 4. The creation of antibacterial fibres through physical adsorption of polyelectrolytes

    Author : Josefin Illergård; Monica Ek; Lars Wågberg; Malmsten Martin; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; antibacterial; polyelectrolyte multilayers; polyvinylamine; contact-active antibacterial surfaces;

    Abstract : Contact-active antibacterial surfaces with irreversibly attached antibacterial com-pounds are a sustainable alternative to traditional biocides. No chemicals are released into nature and the antibacterial mechanism reduces the risk of the evolution of re-sistant bacteria. READ MORE

  7. 5. Exploring bis-MPA Based Dendritic Structures in Biomedicine

    Author : Oliver Andrén; Michael Malkoch; Peter Löwenhielm; Sandra Garcia Gallego; Karen Wooley; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Dendrimers; Polymers; antibacterial; self-assembly; Kemi; Chemistry;

    Abstract : In the last decades there has been significant advances in polymer chemistry. New coupling chemistries, polymerization techniques and accelerated approaches enable researches to push the limits of structural control. READ MORE
