    Sammanfattning : A fundamental tool for containing an epidemic outbreak and mitigating its effects is early diagnostics. Currently, most of the diagnostic tests are performed by trained staff in centralized labs, which are expensive and time-consuming to establish and operate. Lack of access to such facilities could have devastating effects. LÄS MER

    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. 3. Ultra-sensitive measurements of magnetically labelled RCA products in a microfluidic channel using a high-Tc SQUID

    Detta är en avhandling från Gothenburg : Chalmers tekniska högskola

    Författare :Sobhan Sepehri; [2018]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; diagnostics.; high-Tc SQUID; biosensor; magnetic nanoparticle; rolling circle amplification; magnetic bioassay;

    Sammanfattning : The development of a nucleic acid (deoxyribonucleic acid (DNA), ribonucleic acid (RNA)) bioassay based on magnetic nanoparticles (MNPs) with a high-Tc superconducting quantum interference device (SQUID) gradiometer as a magnetic readout is described. The specific binding of the MNPs to the target DNA molecules changes the MNPs size distribution and, therefore, the relaxation dynamics and is measured by magnetic ac susceptometry. LÄS MER
