  1. 1. Optical spectroscopy and fluorescence imaging for cancer diagnostics

    Författare :Pontus Svenmarker; Atomfysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Biomedical optics; Diffuse-reflection spectroscopy; Upconverting nanoparticles; Inverse problem; Fluorescence; Tomography; Imaging; Scattering media; Photon migration; Fysicumarkivet A:2012:Svenmarker;

    Sammanfattning : This work presents optical methods for diagnosing cancer. A complementary method for diagnosing eye cancer was investigated using a technique developed within this work named transscleral optical spectroscopy (TOS). LÄS MER

  2. 2. Towards Undistorted Fluorescence for Tissue Diagnostics and Therapy Monitoring

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

    Sammanfattning : 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.

  3. 3. High-resolution imaging of kidney tissue samples

    Författare :David Unnersjö-Jess; Hans Blom; Lena Scott; Hjalmar Brismar; Peter Hansell; KTH; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Super Resolution Microscopy; Kidney; Imaging; Fluorescence; Kidney development; Calcium; Biologisk fysik; Biological Physics;

    Sammanfattning : The kidney is one of the most important and complex organs in the human body, filtering hundreds of litres of blood daily. Kidney disease is one of the fastest growing causes of death in the modern world, and this motivates extensive research for better understanding the function of the kidney in health and disease.

  4. 4. Model-based Approaches to Diffuse Optical Imaging and Dosimetry

    Författare :Johan Axelsson; Atomfysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; photodynamic therapy; diffuse light propagation; fluorescence; imaging; dosimetry; inverse problem;

    Sammanfattning : The work within this thesis investigates Photodynamic therapy and Fluorescence imaging for therapeutics and visualization of deeply embedded lesions. Photodynamic therapy (PDT) is a cancer treatment modality that can eradicate tumors when light, a photosensible drug and oxygen are present. LÄS MER

  5. 5. Hyaluronan Based Biomaterials with Imaging Capacity for Tissue Engineering

    Författare :Yu Zhang; Dmitri Ossipov; Carsten Werner; Uppsala universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; hyaluronan; hydrogel; scaffold; tissue engineering; imaging; interpenetrating network; MRI; fluorescence imaging; scaffold degradation;

    Sammanfattning : This thesis presents the preparation of hyaluronan-based biomaterials with imaging capability and their application as scaffolds in tissue engineering. First, we have synthesized HA derivatives functionalized with different chemoselective groups. LÄS MER
