  1. 1. Silicon Nanopore Arrays : Fabrication and Applications for DNA Sensing

    Author : Miao Zhang; Jan Linnros; Meni Wanunu; KTH; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; nanopore; array; electrochemical etching; DNA; optics; thermophoresis;

    Abstract : Nanopore biomolecule sensing and sequencing has emerged as a simple but powerful tool for single molecule studies over the past two decades. By elec- trophoretically driving single molecules through a nanometer-sized pore, often sitting in an insulating membrane that separates two buffer solutions, ionic current blockades can be detected to reveal rich information of the molecules, such as DNA length, protein size and conformation, even nucleic acid se- quence.

  2. 2. Fluorescence Probing of DNA Structures in Biology and Nanotechnology

    Author : Peter Sandin; Chalmers University of Technology; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; DNA; Fluorescent DNA base analog; UV‐Vis spectroscopy; DNA nanostructure; self‐assembly; time‐resolved fluorescence spectroscopy;

    Abstract : Much has been learnt about DNA since its structure was discovered about half a century ago. Scientists everlasting urge to look beyond and deeper into the intricate machinery of life, has continuously pushed technology forward. READ MORE

  3. 3. Digital Electrical DNA Sensing

    Author : Maoxiang Guo; Wouter van der Wijngaart; Fredrik Westerlund; KTH; []
    Keywords : DNA detection; thiol-ene-epoxy; rolling circle amplification; digital measurement; DNA stretching; microwell-array; gold nanowires; electrical measurement; specificity; limit of detection; liquid storage; disease diagnosis; lab-on-a-chip; point-of-care.;

    Abstract : Molecule detection is a workhorse in life sciences and medicine, for example in cancer diagnosis and virus and bacterial detection. DNA analysis can provide vital information about the state of a host organism and its medical and health condition. READ MORE

  4. 4. Electric DNA arrays for determination of pathogenic Bacillus cereus

    Author : Yanling Liu; Sven-Olof Enfors; Helena Anderson; KTH; []
    Keywords : MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Bacillus cereus; haemolysin; non-haemolytic enterotoxin; cytotoxin K-2; cereulide; toxin-coding genes; bacterial colony; electric DNA chip; ultrasonication; DNA fragmentation; Biochemistry; Biokemi;

    Abstract : Silicon-based electric chip arrays were developed for characterization of Bacillus cereus with respect to the capacity to produce toxins involved in food poisoning and foodborne infections. Bacteria of the B. cereus group contain different sets of four toxins encoded by eight genes. READ MORE

  5. 5. Biosensing and Protein Array Design using Lipid Assemblies

    Author : Charlotte Larsson; Chalmers University of Technology; []
    Keywords : protein adsorption; protein arrays; lipid bilayer; SPR; scFv; lipid vesicle; DNA arrays; QCM-D;

    Abstract : Biomolecular sensing often includes immobilization of biomolecules, e.g. DNA, antibodies etc., to solid supports, where they act as selective recognition elements. READ MORE
