  1. 16. Hyaluronan Based Biomaterials with Imaging Capacity for Tissue Engineering

    Författare :Yu Zhang; Dmitri Ossipov; Carsten Werner; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; hyaluronan; hydrogel; scaffold; tissue engineering; imaging; interpenetrating network; MRI; fluorescence imaging; scaffold degradation;

    Sammanfattning : This thesis presents the preparation of hyaluronan-based biomaterials with imaging capability and their application as scaffolds in tissue engineering. First, we have synthesized HA derivatives functionalized with different chemoselective groups. LÄS MER

  2. 17. Fixation of Functionalized DNA Nanostructures

    Författare :Erik Lundberg; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; triplex recognition; dna; self-assembly; gel electrophoresis; nanotechnology; cross-linking; spectroscopy; fixation; fret; click chemistry;

    Sammanfattning : This thesis features results from two different studies on a fully addressable non-repetitive network on the nanometre scale, assembled by synthetic DNA molecules. A bio-inspired molecular approach, based on principles of self-assembly, has brought about a paradigm shift in nanoscience, from a top-down to a bottom-up perspective. LÄS MER

  3. 18. Bottom-up Fabrication of Functional DNA Nanostructures

    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; click chemistry; gel electrophoresis; self-assembly; cross-linking; lipid membrane; fixation; linear dichroism; nanotechnology; spectroscopy; fret; dna; triplex recognition;

    Sammanfattning : This thesis demonstrates bottom-up fabrication of a fully addressable non-repetitive network on the nanometer scale, assembled by synthetic DNA molecules. Each side constitutes a unique sequence of 10 bases, i.e. 3. LÄS MER

  4. 19. Surface nanomechanical properties of hydrogels and coatings

    Författare :Gen Li; Per M. Claesson; Jan van Stam; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Nanomechanical properties; nanotribology; nanowear; poly-HEMA; poly-NIPAm; Cellulose nanocrystals; AFM; Kemi; Chemistry;

    Sammanfattning : Characterizing mechanical and wear properties at the nanometer scale emerged as a fascinating and challenging topic in the last decades due to recognition of many interesting and unusual properties of nanomaterials. Due to recent developments of the atomic force microscopy (AFM) technique, it is now possible to measure nanomechanical properties and topography simultaneously, as well as performing and evaluating wear measurements at the nanometer scale.
