2. 1. Adsorption of biopolymers and their layer-by-layer assemblies on hydrophilic surfaces

   Author : Maria Lundin; Eva Blomberg; Thomas Arnebrant; KTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Layer-by-layer; multilayer; adsorption; biopolymers; Chitosan; Heparin; Mucin; Albumin; Lysozyme; β-casein; SDS; QCM-D; Ellipsometri; DPI; TIRF; FRET; SFA; layer structure; solvent content; vertical diffusion; exponential growth; solid-liquid interface; deposition conditions; Surface and colloid chemistry; Yt- och kolloidkemi;

   Abstract : It is widely known that surfaces play an important role in numerous biological processes and technological applications. Thus, being able to modify surface properties provides an opportunity to control many phenomena occurring at interfaces. READ MORE

4. 2. Caveolae associated proteins and how they effect caveolae dynamics

   Author : Björn Morén; Richard Lundmark; Volker Haucke; Umeå universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Caveolae; caveolin; EHD2; cavin; microdomain; microscopy; TIRF; AFM; medicinsk biokemi; Medical Biochemistry;

   Abstract : Caveolae are a type of invaginated membrane domain that has been shown to be involved in several disease states, including lipodystrophy, muscular dystrophies and cancer. Several of these diseases are caused by the lack of caveolae or caveolae-related signaling deficiencies in the tissues in which the caveolar domain are abundant such as lung, adipose, muscle and their related endothelial cells.

5. 3. Modification of Surface Properties Through Polymer Adsorption. Kinetics, Interaction, Degradation and Stability

   Author : Dries Muller; Fysikalisk kemi; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; TIRF.; protein; poly lactide ; poly ethylene oxide ; gelatin; exchange; enzyme; ellipsometry; desorption; degradation; adsorption; copolymers; Physical chemistry; Fysikalisk kemi;

   Abstract : The interfacial behaviour of polymers in relation to surface modification and polymer degradation was studied. In the first part the interfacial behaviour of amphiphilic poly(ethylene oxide)–poly(D,L-lactide) (EmLn) diblock copolymers at hydrophilic and hydrophobic substrates from aquous solution was studied.

6. 4. Probing and elucidating the dynamics of virus-membrane interaction via plasma membrane mimics

   Author : Konrad Thorsteinsson; Marta Bally; Hudson Pace; Gisa Gerold; Susan Daniel; Umeå universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Plasma membrane; supported lipid bilayer; binding kinetics; equilibrium fluctuation analysis; TIRF; FRET; norovirus; HSV; SARS-CoV-2; histo-blood group antigens; ApoE; heparan sulfate; mikrobiologi; Microbiology;

   Abstract : Virus infection is initiated by the attachment of a virion to a susceptible cell’s plasma membrane, in a highly dynamic and well-orchestrated process that encompasses various steps and engages numerous viral and cellular factors. These dynamic steps may include initial non-specific binding to ubiquitous cell-membrane ligands, diffusion across the membrane to a suitable entry site and virus engagement with various receptors and co-receptors on the cell surface.

7. 5. Characterization of artificial and biological lipid vesicles using TIRF and SPR

   Author : Thomas Olsson; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; membrane permeability; chromaffin vesicle; fluorescence; total internal reflection TIRF microscopy; surface plasmon resonance SPR ; vesicle; osmotic shock; cell membrane; liposome; nanoparticle tracking analysis NTA ; large dense core vesicles LDCVs ;

   Abstract : Synthetic lipid vesicles serve as important mimics of cells and the natural membranes that they are enclosed by. As such they are frequently used as simplified models of the highly complex cell membrane to aid in-depth physicochemical and biological characterization of this essential biological structure.
