  2. 1. Antibacterial Strategies for Titanium Biomaterials

    Author : Erik Unosson; Ken Welch; Håkan Engqvist; Timo Närhi; Uppsala universitet; []
    Keywords : 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;

    Abstract : 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. READ MORE

  4. 2. 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

  5. 3. Bioactive Surgical Implant Coatings with Optional Antibacterial Function

    Author : Mirjam Lilja; Maria Strømme; Håkan Engqvist; Håvard Haugen; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Hydroxyapatite; titanium dioxide; photocatalysis; antibacterial effect; antibiotic release; biomimetic coating; co-precipitation; tobramycin;

    Abstract : Device associated infections are a growing problem in the field of orthopaedics and dentistry. Bacteria adhering to implant surfaces and subsequent biofilm formation are challenging to treat with systemic administered antibiotics. READ MORE

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

    Author : Oscar Janson; Ken Welch; Pentti Tengvall; Uppsala universitet; []
    Keywords : 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;

    Abstract : 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. READ MORE

  7. 5. Development of Non-leaching Antibacterial Approaches on Cellulose-based Substrates and Their Mechanisms

    Author : Chao Chen; Monica Ek; Josefin Illergård; Stefan Spirk; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Layer-by-layer; antibacterial; cellulose materials; Chemical Engineering; Kemiteknik;

    Abstract : The layer-by-layer (LbL) technique is becoming a powerful tool that has been applied in many surface coatings and functionalizations in recent years. It has many advantages including a fast and mild process, the flexibility of choice of substrate, and the easiness to scale-up. READ MORE
