  1. 1. Antibacterial Strategies for Titanium Biomaterials

    Författare :Erik Unosson; Ken Welch; Håkan Engqvist; Timo Närhi; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Titanium; silver; biomaterial; antibacterial; photocatalysis; hydrogen peroxide; reactive oxygen species; combinatorial materials science; Engineering Science with specialization in Materials Science; Teknisk fysik med inriktning mot materialvetenskap;

    Sammanfattning : Titanium and titanium based alloys are widely used in dentistry and orthopedics to replace hard tissue and to mend broken bones. It has become a material of choice due to its low density, high strength, good biocompatibility and its capacity to integrate closely with the bone. LÄS MER

  3. 2. The creation of antibacterial fibres through physical adsorption of polyelectrolytes

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

    Sammanfattning : 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. LÄS MER

  4. 3. Bioactive Coatings and Antibacterial Approaches for Titanium Medical Implants

    Författare :Oscar Janson; Ken Welch; Pentti Tengvall; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Bioactivity; antibacterial; titanium; hydrogen peroxide; hydroxyapatite; biomaterial; Teknisk fysik med inriktning mot materialvetenskap; Engineering Science with specialization in Materials Science;

    Sammanfattning : The aim of this thesis was to characterize and manufacture coatings and surfaces with antibacterial properties and retained or enhanced bioactivity and biocompatibility. The aim was also to study the optimal composition and parameters of mixtures for debridement of bacterial biofilms on titanium surfaces. LÄS MER

  5. 4. Antibacterial Surfaces for Biomedical Applications

    Författare :Saba Atefyekta; Chalmers tekniska högskola; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; contact killing surfaces; antibiotic delivery; Antibacterial surfaces; Infection; mesoporous titania; Elastin-like polypeptides; antimicrobial peptides;

    Sammanfattning : Medical devices such as orthopedic implants are intended to serve for improved quality of life. However, clinical success cannot be taken for granted and the most common reason for failure is due to biomaterials associated infection (BAI). LÄS MER

  7. 5. Pilicides and Curlicides : Design, synthesis, and evaluation of novel antibacterial agents targeting bacterial virulence

    Författare :Erik Chorell; Fredrik Almqvist; Stephen Hanessian; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; pilicide; curlicide; anti-virulence; chaperone usher pathway; antibacterial; pili; curli; Escherichia coli; biofilm inhibitor; 2-pyridone; peptidomimetic; Organic chemistry; Organisk kemi; Bioorganic chemistry; Bioorganisk kemi; Pharmaceutical chemistry; Läkemedelskemi; Organic synthesis; Organisk syntes; Infectious diseases; Infektionssjukdomar; Biorganic Chemistry; bioorganisk kemi; Infectious Diseases; infektionssjukdomar; datorlingvistik; computational linguistics; organisk kemi; Organic Chemistry;

    Sammanfattning : New strategies are needed to counter the growing problem of bacterial resistance to antibiotics. One such strategy is to design compounds that target bacterial virulence, which could work separately or in concert with conventional bacteriostatic or bactericidal antibiotics. LÄS MER
