  1. 1. Förster Resonance Energy Transfer - from single molecule spectroscopy to imaging

    Författare :Evangelos Sisamakis; Jerker Widengren; Paul R Selvin; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; FRET; FCS; single-molecule biophysics;

    Sammanfattning : During the last fifteen years several methods have been developed for probing biomolecules (DNA, RNA, proteins) one at a time. Among these methods fluorescence spectroscopy and in particular its many implementations for monitoring Förster Resonance Energy Transfer (FRET), have attracted much interest. LÄS MER

  3. 2. Fluorescence fluctuation studies of biomolecular interactions in solutions, biomembranes and live cells

    Författare :Volodymyr Chmyrov; Jerker Widengren; Antoine Delon; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; FCS; FCCS; Isomerization; TRAST; NMR; FRET; biomombrane; fluidity; Biological Physics; Biologisk fysik;

    Sammanfattning : Fluorescence spectroscopy and imaging have a very broad spectrum of applicationswithin the life sciences, in particular for detection and characterization ofbiomolecular dynamics and interactions in different environments. This thesis comprisesprojects that strive to further expand the information content extracted fromthe detected fluorescence, leading to sensitive readout parameters for studies ofbiomolecular dynamics and interactions.

  4. 3. Investigation of Neuronal Protein Trafficking at the Molecular Scale

    Författare :Martina Damenti; Ilaria Testa; Clive Bramham; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Endoplasmic Reticulum; Mitochondria; Arc Activity-regulated cytoskeleton-associated protein ; oligomerization; pRESOLFT; STED; event-triggered FCS; DNA-PAINT; STARSS; molecular dynamics simulations; Biological and Biomedical Physics; Biologisk och biomedicinsk fysik;

    Sammanfattning : Neurons are polarized cells that encode information in the nervous system viaelectrochemical connections named synapses. The tuning of synapticconnections is enabled by a plastic protein trafficking system which operates atthe nanoscale to finely tweak the neuronal ultrastructure. LÄS MER

  5. 4. Proton transfer across and along biological membranes

    Författare :Johan Berg; Peter Brzezinski; Artur Osyczka; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; biological membranes; cardiolipin; cytochrome bo3; cytochrome c oxidase; energy conversion; fluorescence correlation spectroscopy FCS ; localized coupling; mitochondria; proton transfer; Rcf1; respiration; single-enzyme measurement; Biochemistry; biokemi;

    Sammanfattning : Proton-transfer reactions belong to the most prevalent reactions in the biosphere and make life on Earth possible, as they are central to energy conversion. In most known organisms, protons are translocated from one side of a membrane to the other, which generates an electrochemical gradient that drives ATP synthesis. LÄS MER

  7. 5. Cost-efficient carbon abatement strategies in the EU with specific focus on forest carbon sequestration

    Författare :Miriam Munnich; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : Forests can contribute to the reduction of carbon emissions by storing carbon in standing biomass or in products made of wood. Alternatively, harvested biomass can be used as bioenergy and replace fossil fuels. This thesis analyses the cost-efficiency of introducing forest carbon sequestration (FCS) into EU climate policy.
