  1. 21. Blue Laser Source for Laser-Induced Fluorescence

    Författare :Jesper Holm; Atomfysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Second Harmonic Generation; Lasers; PPKTP; ALA; Tapered laser diodes; External cavity lasers; Laser-induced fluorescence; photodynamic therapy; mTHPC;

    Sammanfattning : Laser-induced fluorescence is a clinical diagnostic tool, used for tumor demarcation and detection. The technique relies on the injection or topical application of a light sensitive drug called a photosensitizer. This substance has the ability to be accumulated to higher concentrations in cancer cells than in normal cells. LÄS MER

  2. 22. Modern Computational Physical Chemistry : An Introduction to Biomolecular Radiation Damage and Phototoxicity

    Författare :Jorge Llano; Leif A. Eriksson; Ulf Ryde; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Biology; statistical mechanics; biophysical chemistry; interface; surface thermodynamics; bioelectrochemistry; ionizing radiation; radiation therapy; condensed matter; computational chemistry; nucleic acids; radiation damage; electrode potential; electronic transport; photochemistry; strand break; photodynamic action; cytostatic; solvation; solvated electron; absolute potential; chemical potential; Biologi; Biology; Biologi;

    Sammanfattning : The realm of molecular physical chemistry ranges from the structure of matter and the fundamental atomic and molecular interactions to the macroscopic properties and processes arising from the average microscopic behaviour.Herein, the conventional electrodic problem is recast into the simpler molecular problem of finding the electrochemical, real chemical, and chemical potentials of the species involved in redox half-reactions.

  3. 23. Transpupillary thermotherapy and photodynamic therapy for neovascular age-related macular degeneration

    Författare :Anne Odergren; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Age-related macular degeneration (AMD) is the leading cause of irreversible blindness among elderly in industrialized nations, and promises to extract an even greater toll with the imminent demographic shift. Neovascular AMD (wet AMD) often develops quickly and involves the growth of new blood vessels under the retina (choroidal neovascularization, CNV). LÄS MER

  4. 24. Multimodal Porphyrin-Based Conjugates : Synthesis and characterization for applications as amyloid ligands, photodynamic therapy agents and chiroptical materials

    Författare :Katriann Arja; Peter Nilsson; Peter Konradsson; Fredrik Almqvist; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Organic compounds that interact both with certain biological targets and display specific photophysical properties can be utilized as molecular tools to visualize and possibly effect disease related processes taking place in living organisms. In this regard, porphyrins are a class of naturally occurring molecules that possess intriguingly interesting photophysical properties where they can act as luminescent probes by emitting detectable light, as well as photosensitizers in the light mediated therapy called photodynamic therapy.

  5. 25. Applications of laser spectroscopy to analytical chemistry, environmental monitoring and medicine

    Författare :Thomas Johansson; Förbränningsmotorer; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; fluorescence; spectroscopic techniques; fluorescence imaging; capillary electrophoresis; acoustic levitation; remote sensing; interstitial photodynamic therapy; multivariate analysis; Laserteknik; Laser technology; tissue optics; medical imaging; Fysicumarkivet A:2002:Johansson;

    Sammanfattning : In this thesis spectroscopic techniques have been used in the fields of analytical chemistry, environmental and medical applications. In analytical chemistry, laser induced fluorescence was used to image the separation of substances during capillary electrophoresis. LÄS MER
