  1. 1. Interaction Between Microgels and Oppositely Charged Peptides

    Författare :Helena Bysell; Martin Malmsten; Per Hansson; Walter Richtering; Uppsala universitet; []
    Nyckelord :MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; antimicrobial peptides; binding; cationic peptides; confocal microscopy; deswelling; distribution; electrostatic; homopolypeptides; microgels; peptides; release; swelling; PHARMACY; FARMACI; Pharmaceutical Physical Chemistry; farmaceutisk fysikalisk kemi;

    Sammanfattning : Lightly cross-linked polyelectrolyte microgels are materials with interesting properties for a range of applications. For instance, the volume of these particles can be drastically changed in response to pH, ionic strength, temperature, or the concentration of specific ions and metabolites. LÄS MER

  2. 2. The creation of antibacterial fibres through physical adsorption of polyelectrolytes

    Författare :Josefin Illergård; Monica Ek; Lars Wågberg; Malmsten Martin; KTH; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; antibacterial; polyelectrolyte multilayers; polyvinylamine; contact-active antibacterial surfaces;

    Sammanfattning : Contact-active antibacterial surfaces with irreversibly attached antibacterial com-pounds are a sustainable alternative to traditional biocides. No chemicals are released into nature and the antibacterial mechanism reduces the risk of the evolution of re-sistant bacteria. LÄS MER

  3. 3. Biomolecular Interactions with Porous Silicon

    Författare :Linda Karlsson; Martin Malmsten; Linköpings universitet; []

    Sammanfattning : One common problem when putting something inside the body is a fast response from the body defending it from the intruder. Here the researchers are struggling with finding biocompatible materials, which act in a predicted and non-harmful way. LÄS MER

  4. 4. Electrochemical Studies of Redox Properties and Diffusion in Self-Assembled Systems

    Författare :Johan Kostela; Mats Almgren; Maja Elmgren; Martin Malmsten; Renata Bilewicz; Uppsala universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Physical chemistry; electrochemistry; self-assembly; bicontinuos cubic phase; redox potential; diffusion; Fysikalisk kemi; Physical chemistry; Fysikalisk kemi;

    Sammanfattning : In this thesis electron transfer reactions and diffusion of redox molecules in three different types of self-aggregated structures are investigated. Electrochemistry was used to investigate the redox potential and diffusion coefficients for redox active molecules with different polarity. The first aggregate system studied was the micellar phase.

  5. 5. Polymeric Nanoparticles as Carriers for Antimicrobial Peptides : Factors Affecting Peptide and Membrane Interactions

    Författare :Randi Nordström; Martin Malmsten; Per Hansson; Helena Bysell; Erica Wanless; Uppsala universitet; []
    Nyckelord :MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; NATURAL SCIENCES; MEDICAL AND HEALTH SCIENCES; antimicrobial peptide; microgel; degradable; nanogel; drug delivery; PEGylation; secondary structure; model membrane; lipid bilayer; neutron reflectometry; ellipsometry; Pharmaceutical Physical Chemistry; Farmaceutisk fysikalisk kemi;

    Sammanfattning : As resistance towards conventional antibiotics is becoming more pronounced, cationic antimicrobial peptides (AMPs) have received considerable attention as possible therapeutic alternatives. Thousands of potent AMPs occur in humans, animals, plants and fungi as a natural part of the immune system. LÄS MER
