  1. 16. Relating the Bulk and Interface Structure of Hyaluronan to Physical Properties of Future Biomaterials

    Författare :Ida Berts; Jöns Hilborn; Adrian R Rennie; Giovanna Fragneto; John W White; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; hyaluronan; structure; bulk; interface; small-angle neutron scattering; neutron reflection; hydrogel; grafting; nanoparticles; protein interactions;

    Sammanfattning : This dissertation describes a structural investigation of hyaluronan (HA) with neutron scattering techniques. HA is a natural biopolymer and one of the major components of the extracellular matrix, synovial fluid, and vitreous humor. LÄS MER

    Sammanfattning : Polysaccharides represent an important resource for a variety of products, from food via fuel supply to functional materials of every kind. Here they are, due to their natural diversity found in many special applications, e.g. in the biomedical sector. LÄS MER

  4. 18. Materials Based on Protein Nanofibrils

    Författare :Xinchen Ye; Mikael S. Hedenqvist; Christofer Lendel; Richard T. Olsson; Jonny Blaker; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; protein nanofibrils; whey protein; hydrogel; film; microfibre; protein structure; mechanical properties;

    Sammanfattning : Protein nanofibrils (PNFs) prepared from whey protein isolate (WPI) at low pH and elevated temperature were processed into materials, i.e. hydrogels, films, foams, and fibres, for different applications where they could potentially be sustainable alternatives to petroleum-based polymers.

  5. 19. Microgel Interactions with Peptides and Proteins : Consequence of Peptide and Microgel Properties

    Författare :Ronja Widenbring; Martin Malmsten; Per Hansson; Catherine Picart; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Binding; Degradation; Enzyme; Gel; Hydrogel; Microgel; Peptide; Protein; Release; Pharmaceutical Physical Chemistry; Farmaceutisk fysikalisk kemi;

    Sammanfattning : Microgels are lightly cross-linked hydrogel particles in the sub-micrometer to micrometer size range with a capacity to drastically change their volume in response to changes in the external environment. Microgels have an ability to bind and store substances such as biomacromolecular drugs, notably proteins and peptides, and release them upon stimuli, making them potential candidates as drug delivery vehicles and functional biomaterials.

  7. 20. Cross-linking and surface properties of EHEC and Starch -a QCM-D study

    Författare :Jesper Hedin; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Hydrogel; GMA; HM-EHEC; Starch; vicoelastic properties; Imidazole; QCM-D; SPR; EHEC;

    Sammanfattning : The increase of the green house gases and the crude oil price has resulted in a willingness to change the raw material in many industries from petroleum-based polymers to natural polymers. One such natural polymer is starch. Today, starch is used in the glue industry in wallpaper pastes. LÄS MER
