  1. 1. Interfacial Properties of Lipid Liquid Crystalline Nanoparticles

    Författare :Pauline Vandoolaeghe; Fysikalisk kemi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; interaction; adsorption; surface; peptide; bilayer; cubic phase; monoolein; cubosome; lipid; liquid crystalline nanoparticles; ellipsometry; neutron reflectivity; QCM-D; SAXD;

    Sammanfattning : Lipid liquid crystalline nanoparticles are studied for their potential as biocompatible carriers for pharmaceutical, food and cosmetic applications. Their potential as delivery vehicles is due to their nanometer size, their controllable structure and physical properties and their large carrying capacity of a wide range of molecules. LÄS MER

  3. 2. Ellipsometry studies of liquid interfaces: New methodology and applications

    Författare :Jan-Willem Benjamins; Fysikalisk kemi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Surface and boundary layery chemistry; Ytkemi; gränsskikt; phospholipids; lactoglobulin; air water; oil water; block copolymers; nonionic surfactants; Brewster angle microscopy; Ellipsometry; adsorption;

    Sammanfattning : Adsorption of several surface active agents, such as nonionics, diblock copolymers, triblock copolymers, proteins and phospholipids at the oil/water and air/water has been studied. In order to be able to do this, a new ellipsometry setup, which utilizes light guides, was developed and tested. LÄS MER

  4. 3. The Co-Structure Directing Agent (CSDA) Approach to Mesoporous Silica Formation – Exploring the Assembly Characteristics

    Författare :Ruiyu Lin; Fysikalisk kemi; []
    Nyckelord :mesoporous silica materials; co-structure directing agent; surfactants; mesostructures; scattering; NMR; TEM;

    Sammanfattning : We investigate the formation mechanism responsible for two specific systems of mesoporous silicas formed with the so-called co-structure directing agent (CSDA) route. The synthesis relies on the interactions between silica source (tetraethylorthosilicate, TEOS), surfactants and CSDA. LÄS MER

  5. 4. Lipid based formulations for topical application: characterization and delivery of active substances

    Författare :Johanna Bender; Chalmers tekniska högskola; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; bicontinuous cubic phase; phytantriol; passive diffusion; bicontinuous sponge phase; stratum corneum; W O microemulsion; monoolein; medium chain triglycerides;

    Sammanfattning : In this thesis, the interaction between lipids, solvents and active substances in lipid based formulations have been studied and related to formulation structure or release behavior on human skin or a model thereof. For the different investigations, isotropic equilibrium lipid phases, i.e. LÄS MER

  7. 5. The skin barrier : structure and physical function

    Författare :Lars Petter Oskar Norlén; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : The objective of the project "The skin barrier - structure and physical function" was to characterise in detail the human skin barrier structurally and functionally. The thesis work includes in-vivo studies, in-vitro studies and studies on pure model systems. LÄS MER
