    Author : Goran Klenkar; Bo Liedberg; Brian MacCraith; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Microarray; biosensor; biomolecular interaction; narcotics detection; imaging ellipsometry and surface plasmon resonance; Molecular biophysics; Molekylär biofysik;

    Abstract : Livet tas för givet av de flesta. Det finns däremot många som ägnar stora delar av sitt liv för att försöka lösa dess mysterier. En del av lösningen ligger i att förstå hur alla molekyler är sammanlänkade i det gigantiska nätverk som definierar den levande organismen. READ MORE

  4. 22. Tunable and modular assembly of polypeptides and polypeptide-hybrid biomaterials

    Author : Christopher Aronsson; Daniel Aili; Karin Enander; Staffan Dånmark; Dennis Löwik; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Biomaterials are materials that are specifically designed to be in contact with biological systems and have for a long time been used in medicine. Examples of biomaterials range from sophisticated prostheses used for replacing outworn body parts to ordinary contact lenses. Currently it is possible to create biomaterials that can e.g. READ MORE

  5. 23. Orientational dynamics of single molecules applied to protein-DNA target search

    Author : Emil Marklund; Johan Elf; Erwin Peterman; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; single molecule imaging; fluorescence correlation spectroscopy; gene regulation; transcription factor; lac operon;

    Abstract : Cells in all life forms regulate their genes with the help of transcription factors (TFs). These proteins turn genes on or off by binding regulatory motifs present in the DNA. Before this binding can occur, a TF needs to search and find the specific binding site in the genome of the cell. READ MORE

  6. 24. Trapping Tyrosine Z : Exploring the Relay between Photochemistry and Water Oxidation in Photosystem II

    Author : Johannes Sjöholm; Stenbjörn Styring; Fikret Mamedov; A. William Rutherford; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Photosystem II; Tyrosine Z; EPR; proton-coupled electron transfer; hydrogen bond; pH;

    Abstract : Photosystem II is unique! It remains the only enzyme that can oxidize water using light as energy input. Water oxidation in photosystem II is catalyzed by the CaMn4 cluster. The electrons extracted from the CaMn4 cluster are transferred to P680+ via the tyrosine residue D1-Tyr161 (YZ). READ MORE

  7. 25. Peptide-Liposome Model Systems for Triggered Release

    Author : Camilla Skyttner; Daniel Aili; Karin Enander; Fredrik Höök; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Liposomes are widely used in drug delivery to improve drug efficacy and to reduce side effects. For liposome-encapsulated drugs to become bioavailable and provide a therapeutic effect they must be released, which typically is a slow process that primarily relies on passive diffusion, liposome rupture or endocytotic uptake.
