  2. 6. Nanostructured surfaces created by the interactions of dendrimers and oppositely charged amphiphiles

    Author : Marianna Yanez; Fysikalisk kemi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; PAMAM; Surfactant; SDS; Lipid; Bilayer; Model Biomembrane; Nucleolipid; DLPA; DLPU; DNA; RNA; Neutron Reflectometry; Poly amidoamine ; Interface; Adsorption; Polyelectrolyte;

    Abstract : The research described in this thesis aims to understand the interactions between cationic poly(amidoamine) (PAMAM) dendrimers and small oppositely charged amphiphiles at the solid-liquid and air-liquid interfaces in relation to the bulk solution behavior. There is high interest in PAMAM dendrimers because they are well-defined polymers with a hierarchical architecture which makes them promising materials as nanocapsules and gene vectors. READ MORE

  4. 7. Lipid-Based Surface Modifications: towards the Development of Membrane-Protein Arrays

    Author : Indriati Pfeiffer; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; DNA-array; cholesterol-DNA; EIS; membrane proteins; lipid vesicles; QCM-D; supported lipid bilayer;

    Abstract : Mimics of the natural cell membrane, such as lipid vesicles and supported lipid membranes, have gained significant attention in recent years. This is primarily due to their ability to provide scientists with a model system allowing a large arsenal of scientific tools to be used in studies of biological reactions that are naturally controlled by the cell membrane and its components.

  5. 8. Supported Lipid Membranes and Their Use for the Characterization of Biological Nanoparticles

    Author : Silver Jõemetsa; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; fluorescence microscopy; supported lipid bilayer; lipophilic dyes; size determination; diffusion; microfluidics;

    Abstract : Biological nanoparticles (BNPs) are nano-sized lipid vesicles of biological origin, which are involved in multiple biological processes. BNP characterization techniques are critical for improving the understanding of how these particles contribute to cellular communication, viral infections and drug-delivery applications. READ MORE

  6. 9. Lipid Vesicle Fusion: Investigation, Generation and Manipulation of Cell-Membrane Mimics

    Author : Lisa Simonsson; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; diffusion; spreading lipid bilayers; cell mimic; micromanipulation; lipid bilayer; microfluidics; site-specificity; DNA; membrane-receptor interactions; total internal reflection fluorescence microscopy; model system; self-assembly; TIRF microscopy; FRET; exocytosis; vesicles; fluorescence resonance energy transfer; biomembranes; amperometry; membrane fusion;

    Abstract : Membrane fusion is essential for nerve-cell communication, for protein transport between cell organelles and the cell-membrane and for enabling the merger between virus and host membranes during virus infection. In this work, cell-membrane mimics were constructed and evaluated as models for studies of the membrane-fusion process. READ MORE

  7. 10. Surface Modifications for Biointerfaces - Supported Lipid Bilayers and some Aspects of Microcontact Printing

    Author : Karin Glasmästar; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; QCM-D; PDMS; cell attachment; supported lipid bilayer; microcontact printing; SPR; ToF-SIMS; protein adsorption; formation kinetics; XPS;

    Abstract : Biointerfaces engage several disciplines: physics, materials science, chemistry, biology and medicine. They are found on the surfaces of implants, tubes and tanks in the food industry or on the hull of a boat. In this work, model surfaces aimed for contact with biological systems were studied.
