  1. 1. Porous materials based on nanopolysaccharides for medical applications: Effect of crosslinking on pore structure and mechanical performance

    Författare :Narges Naseri; Orlando Rojas; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Trä och bionanokompositer; Wood and Bionanocomposites;

    Sammanfattning : The objective of this work was to develop nanochitin- and nanocellulose-based crosslinked porous nanostructured materials for wound dressing and cartilage repair with suitable porosity and mechanical properties to facilitate cell growth. In the first part of the work (papers I-III), chitosan-based nanocomposites loaded with a high concentration (50 wt%) of chitin nanocrystals (ChNC) and cellulose nanocrystals (CNC) were prepared via electrospinning for use as wound dressing materials.

  3. 2. Porous structures based on nanopolysaccharides for medical applications

    Författare :Narges Naseri; Nazanin Emami; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Trä och bionanokompositer; Wood and Bionanocomposites;

    Sammanfattning : Recently, the use of bio-based nanomaterials has attracted much interest in medical applications due to their cytocompatibility, good moisture stability, good mechanical properties, hydrophilic surfaces and their ability to form porous structures. The aim of this work is to develop porous nanocomposites based on nanochitin and nanocellulose with controlled pore size and porosity in order to facilitate cell growth and interconnectivity and to investigate their potential in wound dressing and cartilage regeneration.
