  1. 1. Antimicrobial Polymer Composites for Medical Applications

    Author : Peter Kaali; Sigbritt Karlsson; Ferruccio Doghieri; KTH; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; medical polymers; antimicrobial; body fluids; degradation; Polymer chemistry; Polymerkemi;

    Abstract : The current study and discuss the long-term properties of biomedical polymers in vitro and invivo and presents means to design and manufacture antimicrobial composites. Antimicrobialcomposites with reduced tendency for biofilm formation should lead to lower risk for medicaldevice associated infection. READ MORE

  2. 2. Bio-based nonionic antimicrobial polymers with isatin or indole functionality

    Author : Xiaoya Li; Centrum för analys och syntes; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; antimicrobial polymers; nonionic; isatin; indole; miscibility; hemolytic activity; cytotoxicity;

    Abstract : Infections by pathogenic microorganisms remain one of the most serious concerns in several areas, particularly in hygienic applications. Antimicrobials have been used to combat these infections. Using small molecular antimicrobials as additives or coatings is an industrially adopted strategy. READ MORE

  3. 3. Exploring bis-MPA Based Dendritic Structures in Biomedicine

    Author : Oliver Andrén; Michael Malkoch; Peter Löwenhielm; Sandra Garcia Gallego; Karen Wooley; KTH; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; 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

  4. 4. Superabsorbent Polymers from the Cell Wall of Zygomycetes Fungi

    Author : Akram Zamani; Akram Zamani Forooshani; Högskolan i Borås; []
    Keywords : MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; MEDICIN OCH HÄLSOVETENSKAP; ENGINEERING AND TECHNOLOGY; MEDICAL AND HEALTH SCIENCES; chitosan; cell wall; chitin; polyphosphates; dilute sulfuric acid; zygomycetes fungi;

    Abstract : The present thesis presents new renewable, antimicrobial and biodegradable superabsorbent polymers (SAPs), produced from the cell wall of zygomycetes fungi. The cell wall was characterized and chitosan, being one of the most important ingredients, was extracted, purified, and converted to SAP for use in disposable personal care products designed for absorption of different body fluids.

  5. 5. Wheat Gluten -Based Materials and Composites: Extrusion, Casting and Antimicrobial Properties

    Author : Hasan Türe; Mikael Hedenqvist; José-Maria Lagaron; KTH; []
    Keywords : wheat gluten; extrusion; urea; montmorillonite; sol-gel process; hybrid materials; casting; compression moulding; potassium sorbate; antifungal; plasticiser; thermal; mechanical and barrier properties.;

    Abstract : The use of bio-based polymers as packaging materials has gained much attention due to increasing environmental concerns regarding non-biodegradable petroleum-derived plastics. Wheat gluten (WG) is a valuable renewable resource for the production of bio-based materials because of its low price, biodegradability, good film-forming properties and good gas barrier properties under dry conditions.
