    Sammanfattning : Biomaterials are materials that are specifically designed to be in contact with biological systems and have for a long time been used in medicine. Examples of biomaterials range from sophisticated prostheses used for replacing outworn body parts to ordinary contact lenses. Currently it is possible to create biomaterials that can e.g. LÄS MER

  2. 2. Laser Spectroscopy in Scattering Media for Biological and Medical Applications

    Författare :Linda Persson; Atomfysik; []

    Sammanfattning : Organic electronic materials, that is, carbon-based compounds that conduct electricity, have emerged as candidates for improving the interface between conventional electronics and biological systems. The softness of these materials matches the elasticity of biological tissue better than conventional electronic conductors, allowing better contact to tissue, and the mixed ionic-electronic conductivity can improve the signal transduction between electronic devices and electrically excitable cells.

  4. 4. Biomedical and atmospheric applications of optical spectroscopy in scattering media

    Författare :Johannes Swartling; Atomfysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Turbid media; Tissue optics; Tissue optical properties; Multiple scattering; Radiative transfer; Diffusion equation; Monte Carlo method; Time-resolved spectroscopy; Atomic and molecular physics; Integrating spheres; Atom- och molekylärfysik; Fysicumarkivet A:2002:Swartling;

    Sammanfattning : Spectroscopic analysis of scattering media is difficult because the effective path length of the light is non-trivial to predict when photons are scattered many times. The main area of research for such conditions is biological tissues, which scatter light because of variations of the refractive index on the cellular level. LÄS MER

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

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

    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.
