   Sammanfattning : Protein-based materials, with their unique properties of combining high strength, while maintaining elasticity, and their inherent biocompatibility, hold immense potential for various applications. In order to harness these properties, we need to understand and control how protein building blocks come together to form hierarchically structured materials. LÄS MER

4. 3. Protein Nanomaterials: : Functionalization, Self-assembly, and Applications

   Författare :Lei Wang; Niclas Solin; Olle Inganäs; German Salazar-Alvarez; Linköpings universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

   Sammanfattning : As one of the major classes of materials that is relevant to biological function of our daily life, proteins are highly interesting in both biological and material science. Self-assembled protein amyloid nanostructures have been considered not only as aggregates in pathological tissue, but also as a kind of advanced one dimension materials in material science perspective due to their favorable characteristics including high aspect ratio, abundant surface charge groups, high stability, and tunable surface properties.

5. 4. Bioanalysis using capillary electrophoresis and mass spectrometry : Applied on proteins, protein nanofibrils and polyvinyl alcohol microbubbles

   Författare :Leila Josefsson; Åsa Emmer; Ulrika Nilsson; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; : amyloid; capillary electrophoresis; contrast agents; detection; human blood plasma; ionic liquids; mass spectrometry; microbubbles; polyvinyl alcohol microbubbles; protein nanofibrils; proteins; Kemi; Chemistry;

   Sammanfattning : The sequencing of the genome of various species, including the human species, have led to increased understanding about how a protein structure is generated, and how specific structures are related to the proteins’ functionality. In paper I and II of this thesis, the folding of proteins in vitro to form hierarchical nanostructures, which in vivo often have a pathological effect, have been studied. LÄS MER

7. 5. Plant protein nanofibrils : characterising properties for future food

   Författare :Anja Herneke; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
   Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

   Sammanfattning : This thesis explores the potential of protein nanofibrils (PNFs) as an ingredient to generate structure in food. Proteins from whey and from plants were used to form PNFs, with particular focus on proteins extracted from plants. PNFs were formed by heating (85-90 °C) the proteins at pH 2 for 24-96 h. LÄS MER
