    Sammanfattning : 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. LÄS MER

  4. 3. Porous Amorphous Calcium Carbonate and Phosphate : Synthesis and Application

    Författare :Rui Sun; Ocean Cheung; Maria Strømme; Ken Welch; Denis Gebauer; Uppsala universitet; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; amorphous calcium carbonate; amorphous calcium phosphate; stabilization; crystallization; porous material; drug delivery; gas adsorption; Engineering Science with specialization in Nanotechnology and Functional Materials; Teknisk fysik med inriktning mot nanoteknologi och funktionella material;

    Sammanfattning : The synthesis of porous amorphous calcium carbonate (ACC) and porous amorphous calcium phosphate (ACP) was developed in this thesis. Porous ACC with specific Brunauer–Emmett–Teller (BET) surface area of >350 m2/g was synthesized using a surfactant free approach. The high surface area of porous ACC was related to its nanostructure. LÄS MER

  5. 4. Mesoporous magnesium carbonate : Synthesis, characterization and biocompatibility

    Författare :Sara Frykstrand Ångström; Maria Strømme; Johan Gómez de la Torre; Natalia Ferraz; Mika Lindén; Uppsala universitet; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; mesoporous; magnesium carbonate; pore size control; cytotoxicity; in vivo; skin irritation; acute systemic toxicity; hemocompatibility; Ca2 uptake; solubility enhancement; Engineering Science with specialization in Nanotechnology and Functional Materials; Teknisk fysik med inriktning mot nanoteknologi och funktionella material;

    Sammanfattning : Mesoporous materials constitute a promising class of nanomaterials for a number of applications due to their tunable pore structure. The synthesis of most mesoporous materials involves a surfactant liquid crystal structure to form the pores. LÄS MER

  7. 5. Ion-Crosslinked Nanocellulose Hydrogels for Advanced Wound Care Applications

    Författare :Alex Basu; Natalia Ferraz; Pentti Tengvall; Uppsala universitet; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; nanofibrillated cellulose; wood nanocellulose; ion crosslinking; hydrogel; wound healing; biocompatibility; blood interactions; bacterial interactions; protein carrier; nanotherapeutic; Engineering Science with specialization in Nanotechnology and Functional Materials; Teknisk fysik med inriktning mot nanoteknologi och funktionella material;

    Sammanfattning : A current trend in the field of wound care is the development of wound healing materials that are designed to address specific types of wounds or underlying pathologies to achieve improved healing. At the same time, there is a societal drive to replace synthetic materials with renewable alternatives. LÄS MER
