4. 18. Single Molecule Detection : Microfluidic Automation and Digital Quantification

   Författare :Malte Kühnemund; Mats Nilsson; Ulf Landegren; Sten Linnarsson; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; 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

5. 19. Detection and Characterisation of Salmonella in Animal Feed Samples by PCR-Based Methods

   Författare :Charlotta Löfström; Teknisk mikrobiologi; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Food and drink technology; Livsmedelsteknik; Biotechnology; Bioteknik; Biokemisk teknik; Biochemical technology; Analytisk kemi; Analytical chemistry; mykologi; virologi; bakteriologi; Mikrobiologi; validation; Microbiology; bacteriology; virology; mycology; Salmonella; ribotyping; detection; animal feed; randomly amplified polymorphic DNA; pulsed-field gel electrophorsis; pre-PCR processing; PCR; polymerase chain reaction; genotyping;

   Sammanfattning : Animal feed is a recognised source of Salmonella enterica for farm livestock and may also indirectly cause infection in people consuming foods of animal origin. It is therefore important to have rapid, reproducible and specific methods for the detection of Salmonella in feed, and for the characterisation of strains for further epidemiological investigations or to trace the source of contamination in a production facility.

7. 20. Biological Sensing and DNA Templated Electronics Using Conjugated Polymers

   Författare :Per Björk; Olle Inganäs; Wolfgang Fritzsche; Linköpings universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; conjugated polymer; conjugated polyelectrolyte; DNA; sensor; nanowire; Bioengineering; Bioteknik;

   Sammanfattning : Conjugated polymers have been found useful in a wide range of applications such as solar cells, sensor elements and printed electronics, due to their optical and electronic properties. Functionalization with charged side chains has enabled water solubility, resulting in an enhanced interaction with biomolecules. LÄS MER
