  1. 16. Microgels as Carriers for Antimicrobial Peptides : Surface-bound microgels, and factors affecting peptide interactions

    Författare :Lina Nyström; Martin Malmsten; Per Hansson; L. Andrew Lyon; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Antimicrobial peptides; Biomaterial coating; Drug delivery; Host defence peptides; Microgels; pH-responsive; Surface-bound; Pharmaceutical Physical Chemistry; Farmaceutisk fysikalisk kemi;

    Sammanfattning : With a growing number of multi-resistant bacteria against conventional antibiotics, there is an urgent need to identify new antimicrobial therapeutics. One example that has gained considerable interest is antimicrobial peptides (AMPs). LÄS MER

  3. 17. De Novo Design and Characterization of Surface Binding Peptides - Steps toward Functional Surfaces

    Författare :Patrik Nygren; Bengt-Harald Jonsson; Klas Broo; Linda Andersson; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Peptide; design; nanoparticle; CD; Amino acid; Organic chemistry; Organisk kemi;

    Sammanfattning : The ability to create surfaces with well-defined chemical properties is a major research field. One possibility to do this is to design peptides that bind with a specific secondary structure to silica nanoparticles. LÄS MER

  4. 18. 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.

  5. 19. Elastic properties of suspended graphene

    Författare :Daniel Midtvedt; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : This thesis concerns describing the mechanical properties of the two dimensional material graphene by continuum elasticity theory. In particular, Nano ElectroMechanical Systems (NEMS) where part of the graphene sheet is made suspended, are considered. LÄS MER

  7. 20. Synchrotron X-ray Scattering and Monte Carlo Simulations of Structure and Forces in Silicate Nanoplatelet Dispersions

    Författare :Mo Segad; Beräkningskemi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; SAXS; MC simulations; Swelling; Tactoids; EXAFS; DLS; Cryo-TEM; Nanoplatelets; MX80; Na Ca montmorillonite.;

    Sammanfattning : Clays are the world’s most widely used natural material, however, little is known regarding the microstructure as well as the forces involved in clay-water interactions, and their influence on the swelling properties. The utilization of clay platelets is nowadays a key in a number of biological and industrial applications e.g. LÄS MER
