  1. 1. Tunable and modular assembly of polypeptides and polypeptide-hybrid biomaterials

    Författare :Christopher Aronsson; Daniel Aili; Karin Enander; Staffan Dånmark; Dennis Löwik; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    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; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Instrumentation technology; Mät- och instrumenteringsteknik; Atom- och molekylärfysik; Atomic and molecular physics; Fysik; Physics; Monte Carlo simulations; Biomedical Optics; Scattering media; Gas measurements; Near infrared spectroscopy; Diode laser spectroscopy; Absorption spectroscopy;

    Sammanfattning : Tunable diode laser absorption spectroscopy can be utilised for gas detection in biological and medical applications. The common approach is to analyse transmitted light according to the Beer-Lambertian law. LÄS MER

  3. 3. Organic electronics for precise delivery of neurotransmitters

    Författare :Amanda Jonsson; Magnus Berggren; Daniel Simon; Marco Rolandi; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    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. Development of Techniques for Characterization, Detection and Protein Profiling of Extracellular Vesicles

    Författare :Sara Cavallaro; Jan Linnros; Apurba Dev; Hakho Lee; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; extracellular vesicles; streaming current; fluorescence microscopy; atomic force microscopy; scanning electron microscopy; protein profiling; size profiling; Biological and Biomedical Physics; Biologisk och biomedicinsk fysik;

    Sammanfattning : Nanosized extracellular vesicles (EVs, ∼30-2000 nm) have emerged as important mediators of intercellular communication, offering opportunities for both diagnostics and therapeutics. In particular, small EVs generated from the endolysosomal pathway (∼30-150 nm), referred to as exosomes, have attracted interest as a suitable biomarker for cancer diagnostics and treatment monitoring based on minimally invasive liquid biopsies.

  5. 5. Bridging Single-Particle Characterisation Gaps of Optical Microscopy in the Nano-Submicron Regime

    Författare :Erik Olsén; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; holography; particle shape; dynamics; Optical microscopy; particle tracking; size estimation; iSCAT; material sensitivity;

    Sammanfattning : As the practical importance of particles in the nano-submicron size regime continues to increase in both biomedical applications and industrial processes, so does the need for accurate and versatile characterisation methods. Optical scattering microscopy methods are commonly used for single-particle characterisation as they provide quick measurements at physiologically relevant conditions with detection limits reaching down to individual biomolecules.
