  2. 1. Towards atomically resolved magnetic measurements in the transmission electron microscope : A study of structure and magnetic moments in thin films

    Author : Hasan Ali; Klaus Leifer; Peter Van Aken; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Transmission electron microscope; thin films; magnetic moments; electron energy loss spectroscopy; simultaneous acquisition; electron magnetic circular dichroism; Teknisk fysik med inriktning mot materialanalys; Engineering Science with specialization in Materials Analysis;

    Abstract : The magnetic properties of thin metallic films are significantly different from the bulk properties due to the presence of interfaces. The properties shown by such thin films are influenced by the atomic level structure of the films and the interfaces. READ MORE

  4. 2. Detection of Biomolecules Using Volume-Amplified Magnetic Nanobeads

    Author : Teresa Zardán Gómez de la Torre; Maria Strømme; Peter Svedlindh; Mikkel Fougt Hansen; Uppsala universitet; []
    Keywords : 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;

    Abstract : 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. READ MORE

    Abstract : Diagnostic ultrasound (US) is safer, quicker and cheaper than other diagnostic imaging modalities. Over the past two decades, the applications of US imaging has been widened due to the development of injectable, compressible and encapsulated microbubbles (MBs) that provide an opportunity to improve conventional echocardiographic imaging, blood flow assessment and molecular imaging.
