  2. 16. Polypeptide functionalized gold nanoparticles for bioanalytical applications

    Author : Robert Selegård; Bo Liedberg; Karin Enander; Daniel Aili; Wilhelm Robert Glomm; Linköpings universitet; []
    Keywords : ;

    Abstract : Detection strategies that allow for simple, rapid, cost efficient and sensitive monitoring of proteins and their interactions with biomolecules are of great importance in drug development and diagnostics. This thesis describes the development of bioanalytical applications based on the tunable self-assembly of gold nanoparticles functionalized with a de novo designed polypeptide. READ MORE

  4. 17. Physiologically based modelling of nanoparticle biodistribution and biokinetics

    Author : Ulrika Carlander; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : To predict the toxicity of nanoparticles (1-100 nm), it is crucial to understand their biokinetics i.e. how they are taken up, distributed, dissolved and removed from the body. Such information can be gained from biodistribution studies in animals. READ MORE

  5. 18. Self-organization of nanoparticles - implications for interface biology

    Author : Anders Lundgren; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Gold nanoparticles; self-organization; self-assembly; nanostructure; nanopatterns; cell surface interactions; chemical gradients;

    Abstract : Cells bind to their surroundings via proteins displayed on the cell surface. These interactions support the cells and are important for many cellular processes, e.g. cell migration during morphogenesis, wound healing and cancer metastasis. READ MORE

  6. 19. Creating Ultrafast Biosensors for Neuroscience

    Author : Yuanmo Wang; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; quantification; glucose; choline oxidase; gold nanoparticles; enzyme monolayer; enzymatic activity; Biosensor; adsorption; brain slice; enzyme stability; acetylcholine esterase; artificial cell; exocytosis; glucose oxidase; deformation; glutamate; glutamate oxidase; acetylcholine; amperometry;

    Abstract : Neuronal communication is the basis for all our brain function and relies on regulated exocytosis, a cell function that involves release of quantal amounts of neurotransmitters into the gap space between interconnected neurons to serve as chemical signals. To study exocytosis, which is a fast process that occurs on the timescale of sub-milliseconds to milliseconds, a toolbox of analytical methods has been developed where the electrochemical based techniques offer quantitative and sufficient high temporal recording speed.

  7. 20. Attenuation of acute inlammatory responses by surface nanotopography

    Author : Mats Hulander; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Gold nanoparticles; nanotopography; gradient nanotopography; immune complement; platelets;

    Abstract : The interaction between biology and non-viable surfaces is crucial for many organisms and cells. For example, bacterial cells need to adhere to mineral surfaces in the soil, plants climb and adhere to walls and marine organisms produce adhesives to cling to underwater rocks etc. READ MORE
