2. 1. De Novo Design and Characterization of Surface Binding Peptides - Steps toward Functional Surfaces

   Author : Patrik Nygren; Bengt-Harald Jonsson; Klas Broo; Linda Andersson; Linköpings universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Peptide; design; nanoparticle; CD; Amino acid; Organic chemistry; Organisk kemi;

   Abstract : The ability to create surfaces with well-defined chemical properties is a major research field. One possibility to do this is to design peptides that bind with a specific secondary structure to silica nanoparticles. READ MORE

4. 2. True Monoliths as Separation Media : Homogeneous Gels for Electrophoresis and Electrochromatography in the Capillary and Microchip Modes

   Author : Ákos Végvári; Douglas Westerlund; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Biochemistry; capillary electrophoresis; capillary electrochromatography; gel electrophoresis; agarose; polyacrylamide; b-cyclodextrin; DNA; peptide; glutathione; drug enantiomers; microchip; Biokemi; Biochemistry; Biokemi; biokemi; Biochemistry;

   Abstract : The thesis focuses on the development of new homogeneous gels for the separation of drug enantiomers, peptides, DNA and virus by electrophoresis and electrochromatography in capillaries and microchips. This type of separation media offers high resolution and small zone broadening. READ MORE

5. 3. Interactions of the Cell-Penetrating Peptide Penetratin with Model Membranes and Live Cells

   Author : Daniel Persson; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; antisense; antennapedia homeodomain; delivery vector; cell-penetrating peptide; protein transduction; uptake; membrane translocation; penetratin; confocal microscopy; vesicle;

   Abstract : The delivery of large, hydrophilic molecules, such as proteins and oligonucleotides, to the cytoplasm and nucleus of cells is problematic due to their generally low plasma membrane permeability. With the identification of a number of cell-penetrating peptides, capable of mediating non-endocytotic, intracellular delivery of macromolecular cargos, this obstacle now seems surmountable.

6. 4. Strategies for developing peptide and protein selective plastic antibodies

   Author : Rashmi Mahajan; Ian A. Nicholls; Subramanian Suriyanarayanan; Börje Sellergren; Alessandra Maria Bossi; Linnéuniversitetet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Competitive assays; molecularly imprinted polymer; magnetic nanoparticle; nanogel; nanoparticle; plastic antibody; solid-phase synthesis; QCM.; Biokemi; Biochemistry;

   Abstract : The objective of the thesis was to explore approaches for the development of molecularly imprinted materials with predetermined selectivity for peptide or protein targets. In particular, the work has focused on molecularly imprinted nanoparticles synthesized using solid-phase synthesis protocols. READ MORE

7. 5. Polypeptide-Based Nanoscale Materials

   Author : Daniel Aili; Bo Liedberg; Karin Enander; Molly Stevens; Linköpings universitet; []
