  2. 1. Interaction Between Antimicrobial Peptides and Phospholipid Membranes : Effects of Peptide Length and Composition

    Author : Lovisa Ringstad; Martin Malmsten; Per Hansson; Jeremy Ramsden; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Adsorption; antibacterial; antimicrobial peptide; bilayer; ellipsometry; electrochemistry; electrostatic interactions; hydrophobicity; liposome; membrane; monolayer; phospholipid; secondary structure; supported bilayer.; PHARMACY; FARMACI; Pharmaceutical Physical Chemistry; farmaceutisk fysikalisk kemi;

    Abstract : Due to increasing problems with bacterial resistance development, there is a growing need for identifying new types of antibiotics. Antimicrobial peptides constitute an interesting group of substances for this purpose, since they are believed to act mainly by disrupting the bacterial membrane, which is a fast and non-specific mechanism.

  4. 2. On the Formation of Supported Phospholipid Bilayers

    Author : Erik Reimhult; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; vesicle adsorption; formation kinetics; SPR; QCM-D; SPB; AFM; supported lipid bilayer; supported membrane; liposome;

    Abstract : Lipid bilayers are a central component of both the structure and function of biological membranes, like the one surrounding cells of living organisms. Since the lipid bilayer provides a host matrix for membrane proteins, which perform many of the specialized tasks in cells like energy, signal and material transduction, researchers have tried to develop artificial model membranes to study a variety of membrane protein functions.

  5. 3. Mesoporous supported lipid bilayers

    Author : Maria Claesson; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; FRAP; Lipid bilayer; Mesoporous; AFM; Vesicle; Titania; Silica; QCM-D;

    Abstract : AbstractLipid bilayers are commonly used as simplified model systems of living cell membranes. They have shown to be important components in the development of biosensing devices where the bilayer acts as a host for transmembrane proteins, such as ion channels, that are utilized as sensing elements.

  7. 5. 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
