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

    Author : Lina Nyström; Martin Malmsten; Per Hansson; L. Andrew Lyon; Uppsala universitet; []
    Keywords : 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;

    Abstract : 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). READ MORE

  4. 2. Interaction Between Microgels and Oppositely Charged Peptides

    Author : Helena Bysell; Martin Malmsten; Per Hansson; Walter Richtering; Uppsala universitet; []
    Keywords : 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;

    Abstract : 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. READ MORE

  5. 3. On the Phase Behaviour of Soft Matter: Understanding Complex Interactions via Quantitative Imaging

    Author : Maxime Bergman; Fysikalisk kemi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Microgels; Lysozyme; eye lens proteins; confocal microscopy; interaction potential; phase behaviour; simulations;

    Abstract : The effect of microscopic colloid interactions on the resultant macroscopic phase behaviour is a frequently studied topic in soft matter resarch, and lies at the heart of this thesis. Key structural and dynamic properties of colloidal model systems across liquid-solid transitions are tracked using optical imaging techniques. READ MORE

  6. 4. Microgels as drug delivery vehicles : loading and release of amphiphilic drugs

    Author : Yassir Al-Tikriti; Per Hansson; Magnus Bergström; Matthew Libera; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; microgel; amphiphilic drug; phase separation; micropipette; Raman microscopy; controlled release; drug delivery; SAXS; Pharmaceutical Physical Chemistry; Farmaceutisk fysikalisk kemi;

    Abstract : Polyelectrolyte microgels are used as delivery vehicles for amphiphilic drugs in, e.g., treatments of liver cancer by a method called trans-arterial chemoembolization. READ MORE

  7. 5. A microfluidic toolbox to fabricate, sort and characterize thermoresponsive colloidal molecules and their assemblies

    Author : Feifei Peng; NanoLund: Centre for Nanoscience; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Microgels; Thermoresponsive Colloidal Molecules; Microfluidics; Self-Assembly; Microgels; Thermoresponsive Colloidal Molecules; Microfluidics; Self-Assembly;

    Abstract : In this thesis we discuss the assembly of thermoresponsive microgel particles into small clusters, and their use as colloidal molecules with specific and directional interactions. The underlying goal is to use these particles as advanced building blocks for new types of self- assembled structures with novel or vastly improved properties, and as model particles for investigating fundamental problems in condensed matter physics.
