  2. 1. 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

  4. 2. The type I-E CRISPR-Cas system : Biology and applications of an adaptive immune system in bacteria

    Author : Lina Amlinger; Magnus Lundgren; Peter Fineran; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; CRISPR; CRISPR-Cas; virus defense; bacteria; bacteriophage; adaptation; spacer integration; interference; gene silencing; fluorescent reporter; Escherichia coli; Mikrobiologi; Microbiology;

    Abstract : CRISPR-Cas systems are adaptive immune systems in bacteria and archaea, consisting of a clustered regularly interspaced short palindromic repeats (CRISPR) array and CRISPR associated (Cas) proteins. In this work, the type I-E CRISPR-Cas system of Escherichia coli was studied.CRISPR-Cas immunity is divided into three stages. READ MORE

  5. 3. Microfluidic Devices for Manipulation and Detection of Beads and Biomolecules

    Author : Mats Jönsson; Ulf Lindberg; Bertil Hök; Johan Nilsson; Uppsala universitet; []
    Keywords : Engineering physics; sensor; micro; dielectrophoresis; impedance; electrode; beads; cell; flow; bacteria; microfabrication; biosensor; electrocapture; microfluidic; planar; Lab on chip; µTAS; micro total analysis system; QCM; dispersion; field-flow fractionation; ITO; design; fabrication; Teknisk fysik;

    Abstract : This thesis summarises work towards a Lab-on-Chip (LOC). The request for faster and more efficient chemical and biological analysis is the motivation behind the development of the LOC-concept. Microfluidic devices tend to become increasingly complex in order to include, e.g. READ MORE

  6. 4. Electrochemical (bio-)sensors operating in human physiological fluids

    Author : Carolin Psotta; Sergey Shleev; Magnus Falk; Evgeny Katz; Malmö universitet; []
    Keywords : biosensor; bacteria; enzyme; sensor; physiological fluid;

    Abstract : This thesis is focused on developing electrochemical (bio-)sensors specifically designed to detect biomolecules and bacteria in human physiological fluids. A more comprehensive understanding of their performance can be obtained by exposing the sensors to real human physiological fluids. READ MORE

  7. 5. Oviposition cues as a tool for developing a new malaria control strategy

    Author : Lynda Eneh; Anna-Karin Borg-Karlson; Willem Takken; KTH; []
    Keywords : Anopheles gambiae; Malaria; Oviposition; Volatile compounds; GC-MS; DGGE; Sorption; Fungi; Bacteria; Physicochemical parameters; Nut grass; Bermuda grass; Anopheles gambiae; Malaria; Äggläggning; Flyktiga ämnen; GC-MS; DGGE; Sorptionen; Svampar; Bakterier; Gräs; Kemi; Chemistry;

    Abstract : Anopheles gambiae sensu lato mosquitoes are among the dominant malaria vectors in sub-Saharan Africa. However, not much is known about the oviposition behaviour of these species necessary for the development of malaria vector control strategies. READ MORE
