  2. 1. Two-Photon Excited Fluorescence Depolarisation : Experimental and Theoretical Development

    Author : Linus Ryderfors; Emad Mukhtar; Lennart B.-Å. Johansson; Yehudi K. Levine; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Two-photon excitation; Fluorescence; Fluorescence depolarisation; Fluorescence anisotropy; Time-correlated single photon counting; Gold nanoparticles; Rotational diffusion; Excited state symmetry; Extended Förster theory; Orientation correlation functions; Donor-donor energy migration DDEM ; Chemical physics; Kemisk fysik;

    Abstract : We have studied fundamental aspects of time-resolved two-photon excited fluorescence depolarisation. The thesis presents experimental as well as theoretical progress. READ MORE

  4. 2. Live Single Cell Imaging and Analysis Using Microfluidic Devices

    Author : Mohammad Ali Khorshidi; Helene Andersson-Svahn; Håkan Jönsson; Carolina Wählby; Johan Elf; KTH; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Single cell analysis; time-lapse fluorescence imaging; automated image analysis; microwell; droplet microfluidics; NK cells; single cell tracking; migration behavior analysis; cell-cell interaction; optical microscopy; image analysis; image processing; microfluidics; immune cells; tracking; counting; morphology analysis;

    Abstract : Today many cell biological techniques study large cell populations where an average estimate of individual cells’ behavior is observed. On the other hand, single cell analysis is required for studying functional heterogeneities between cells within populations. READ MORE

  5. 3. Towards Undistorted Fluorescence for Tissue Diagnostics and Therapy Monitoring

    Author : Haiyan Xie; Atomfysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; upconversion; upconverting nanoparticles; fluorescence-guided-surgery; fluorescence diagnostics; photodynamic therapy; multi-spectral imaging; spectroscopy; biomedical optics; fluorescence; Fysicumarkivet A:2014:Xie;

    Abstract : Fluorescence techniques for applications in tissue diagnostics and therapy monitoring were investigated and developed in the work presented in this thesis. The aim was to develop fluorescence diagnostics for the detection of malignant tumors and better delimitation of the tumor margins, using the enhanced contrast in fluorescence between tumor and surrounding healthy tissue.

  6. 4. Metabolic analysis of shikimic acid producing Escherichia coli

    Author : Louise Johansson; Avdelningen för kemiteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Kemiteknik och kemisk teknologi; Biokemi; metabolism; Chemical technology and engineering; transcriptome analysis; phosphorus-limitation; carbon-limitation; fed-batch; chemostat; batch; fermentation technology; Escherichia coli; shikimic acid; Biotechnology; Bioteknik; Metabolism; Biochemistry; principal component analysis; 2D-fluorescence spectrophotometry; metabolic flux analysis; carbon-rich;

    Abstract : Shikimic acid production using recombinant E.coli has been developed during the past 15 years due to the increased demand of this product, primarily as a starting material for the anti-influensa medicine Tamiflu?. A detailed metabolic analysis of a shikimic acid producing E. READ MORE

  7. 5. Nucleic acid analysis tools : Novel technologies and biomedical applications

    Author : Iván Hernández-Neuta; Mats Nilsson; Frank Bier; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Nucleic acid analysis; padlock probes; selector probes; rolling circle amplification; microfluidics; single-molecule detection; digital quantification; fluorescence microscopy; mobile phone microscopy; molecular diagnostics; virology; Biochemistry; biokemi;

    Abstract : Nucleic acids are fundamental molecules of living organisms functioning essentially as the molecular information carriers of life. From how an organism is built to how it responds to external conditions, all of it, can be found in the form of nucleic acid sequences inside every single cell of every life form on earth. READ MORE
