1. 1. Analysis of Fluorescence Flicker as a Tool to Monitor Proton Transport and Biomolecular Interactions

   Författare :Tor Sandén; Jerker Widengren; Pär Nordlund; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Physics; Fysik;

   Sammanfattning : The overall focus of this thesis is on fluorescence flicker processes of fluorescent molecules, e.g. protonation-deprotonation or singlet-triplet electronic state transitions, intrinsic or generated by their interaction with their environment, monitored by fluorescence spectroscopy.

3. 2. Monitoring Proton Exchange and Triplet States with Fluorescence

   Författare :Tor Sandén; Jerker Widengren; Vogel Horst; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; fluorescence correlation spectroscopy; proton transfer; cytochrome c oxidase; transient state imaging; modulated excitation; Optics; Optik; Biochemistry; Biokemi;

   Sammanfattning : Fluorescent molecules commonly shift to transient dark states, induced bylight or triggered by chemical reactions. The transient dark states can beused as probes of the local environment surrounding the fluorescent molecules,and are therefore attractive for use in biomolecular applications. LÄS MER
