  1. 1. Single Molecule Detection : Microfluidic Automation and Digital Quantification

    Författare :Malte Kühnemund; Mats Nilsson; Ulf Landegren; Sten Linnarsson; Uppsala universitet; []
    Nyckelord :MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICAL AND HEALTH SCIENCES; single molecule; digital; rolling circle amplification; magnetic particle; padlock probe; microfluidics; resistive pulse sensing; lab on chip; mobile phone microscopy; enrichment; sequencing;

    Sammanfattning : Much of recent progress in medical research and diagnostics has been enabled through the advances in molecular analysis technologies, which now permit the detection and analysis of single molecules with high sensitivity and specificity. Assay sensitivity is fundamentally limited by the efficiency of the detection method used for read-out. LÄS MER

  2. 2. Single molecule dynamics

    Författare :Lars Edman; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP;

    Sammanfattning : Properties found in an ensemble of molecules may not be understood if it is not possible to study each molecule one by one. This thesis is concerned with the study of the dynamic properties of individual complex biological molecules as observed by confocal single-molecule fluorescence spectroscopy. LÄS MER

  3. 3. Genotyping and Mutation Detection In Situ : Development and application of single-molecule techniques

    Författare :Ida Grundberg; Mats Nilsson; Ulf Landegren; Olli-Pekka Kallioniemi; Uppsala universitet; []
    Nyckelord :MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; padlock probes; in situ; rolling circle amplification; mRNA; genotyping; mutation detection; cancer; tissue sections; diagnostics; single-molecule; single-cell; microscopy; Molecular medicine genetics and pathology ; Molekylär medicin genetik och patologi ; Molekylär medicin; Molecular Medicine;

    Sammanfattning : The human body is composed of trillions of cells closely working together to maintain a functional organism. Every cell is unique in molecular composition and can acquire genetic variations that might cause it to turn pathological. LÄS MER

  4. 4. Probing Biomolecular Recognition at the Single Molecule Level

    Författare :Anders Gunnarsson; Chalmers University of Technology; []
    Nyckelord :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

  5. 5. Overstretching short DNA – Single-molecule force spectroscopy studies

    Författare :Niklas Bosaeus; Chalmers University of Technology; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; DNA stretching; mechanical properties of DNA; single molecule; optical tweezers; DNA structure;

    Sammanfattning : Structural deformation of DNA has a central role in many biological processes. It occurs, for example, during replication, transcription, and regulation of the activity of the genome. To understand these fundamental processes it is necessary to have a detailed knowledge of the mechanical properties of DNA. LÄS MER
