  1. 16. Detection of Biomolecules Using Volume-Amplified Magnetic Nanobeads

    Författare :Teresa Zardán Gómez de la Torre; Maria Strømme; Peter Svedlindh; Mikkel Fougt Hansen; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Magnetic biosensor; magnetic nanobeads; Brownian relaxation; padlock probe; rolling circle amplification; DNA detection; protein detection; Engineering Science with specialization in Nanotechnology and Functional Materials; Teknisk fysik med inriktning mot nanoteknologi och funktionella material;

    Sammanfattning : This thesis describes a new approach to biomolecular analysis, called the volume-amplified magnetic nanobead detection assay (VAM-DNA). It is a sensitive, specific magnetic bioassay that offers a potential platform for the development of low-cost, easy-to-use diagnostic devices. LÄS MER

  3. 17. Optical Dyes for Visualization of Structure and Function of Biomolecules and Biological Membranes

    Författare :Maria Matson; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Orientation; RNA; Lipid Membranes; Voltage-Sensitive Dyes; Binding Preferences; Cellular Localization; DNA; Spectroscopy; Spectral Properties; Lipophilic Ruthenium Complex;

    Sammanfattning : To visualize the structure and function of biomolecules and biological membranes in the cell, optical dyes are important tools where in particular fluorescent probes provide a sensitive and selective detection. When cellular compartments are investigated it is crucial that the probe selectively binds to the area of interest and not exhibits unspecific binding affinity. LÄS MER

  4. 18. Protein Microarrays Based on Single Framework Recombinant Antibody Fragments (SINFABS) - Catcher and Carrier - A Crucial Combination

    Författare :Cornelia Steinhauer; Institutionen för immunteknologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Immunology; serology; transplantation; Immunologi; serologi; probe; coupling chemistry; solid support; stability; scFv; antibody microarray; protein microarray; Biotechnology; Bioteknik;

    Sammanfattning : Antibody-based microarrays are among the novel class of rapidly evolving proteomic technologies. In recent years, antibody microarrays have emerged as a unique tool for high-throughput protein expression profiling with great promise within biomedicine and a wide range of potential applications, including disease diagnostics and biomarker discovery.

  5. 19. Readout Strategies for Biomolecular Analyses

    Författare :Jenny Göransson; Mats Nilsson; Charles Cantor; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Padlock probe; Selector probe; Rolling circle amplification; Single molecule detection; Amplified single molecule; Random array; Molecular medicine genetics and pathology ; Molekylär medicin genetik och patologi ;

    Sammanfattning : This thesis describes three readout formats for molecular analyses. A common feature in all works is probing techniques that upon specific target recognition ideally results in equimolar amounts of DNA circles. These are then specifically amplified and detected using any of the techniques presented herein. LÄS MER

  7. 20. Probing Biomolecular Recognition at the Single Molecule Level

    Författare :Anders Gunnarsson; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; cell membrane; TIRFM; liposome; time-of-flight secondary ion mass spectrometry; membrane receptor; single molecule; TOF-SIMS; molecular recognition; DNA; barcode; total internal reflection; multiplexing;

    Sammanfattning : Specific recognition between biomolecular partners contributes to a multitude of biochemical signaling within and between cells. The aim of this work has been to investigate the possibility to probe biomolecular recognition reactions at the smallest possible scale, the single molecule level. LÄS MER
