  1. 16. Artificial receptors: New opportunities for the exploitation of molecularly imprinted polymers

    Författare :Lei Ye; Tillämpad biokemi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Radioimmunoassay; Microsphere; Molecular imprinting; Drug determination; Cross-linking polymerisation; Combinatorial library; Chromatography; Chiral separation; Affinity adsorbent; Biosensor; Receptor; Biochemistry; Metabolism; Biokemi; metabolism; Biotechnology; Bioteknik;

    Sammanfattning : Molecular imprinting, method for creating artificial receptors that are mimics of biological antibodies and receptors, is based on the concept of creating substrate-specific recognition sites in polymeric matrices by means of template polymerisation. The polymeric receptors produced display favourable binding characteristics, such as high affinity and specificity towards the substrate molecules. LÄS MER

  3. 17. Molecular Recognition Studies Based on Imprinting Technology

    Författare :Cong Yu; Tillämpad biokemi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; imprinting; molecular recognition; polymer; chiral separation; acrylamide; chromatography; functional monomer; cross-linking; hydrogen bonding; hydrophobic interactions; aqueous media; solvent; antibody; mimics; receptor; artificial enzyme; Bioteknik; Biotechnology; Biokemi; Metabolism; Biochemistry;

    Sammanfattning : In this thesis, I have focused on five main research areas: 1). A new type of imprinted polymer has been developed, namely the amide MIP. The amide functional monomers showed better hydrogen bonding capabilities in polar organic solvents and the resulting polymers exhibited good enantiomeric recognition properties in organic media.

  4. 18. Vitreoscilla hemoglobin. In vitro mutagenesis and transcript profiling to improve its biotechnological usefulness

    Författare :Charlotte Andersson; Tillämpad biokemi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Biochemical technology; Biokemisk teknik; gene expression analysis; transcript profiling; microarray; DNA chips; microaerobic; hypoxia; oxygen-limited; bacterial hemoglobin; Escherichia coli; Vitreoscilla hemoglobin VHb ;

    Sammanfattning : Vitreoscilla is an obligate aerobic bacterium found in oxygen-poor environments such as stagnant ponds and decaying vegetable matter. Vitreoscilla induces the production of a homodimeric hemoglobin (VHb) when subjected to oxygen-limiting conditions. LÄS MER

  5. 19. Development of Transgenic Potatoes to Attain Novel Starch Qualities

    Författare :Mariette Andersson; Tillämpad biokemi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Livsmedelsteknik; Food and drink technology; Biokemisk teknik; Biochemical technology; StGH; starch yield; RNAi; antisense; gene silencing; ahas; potato transformation; sbe2; sbe1; gbss; amylopectin; amylose; Starch; potato;

    Sammanfattning : Starch is a plant-derived polysaccharide with many uses in different food and non-food applications. In this thesis, the production of two novel potato starch qualities, amylopectin and high-amylose, and the modifications and the characteristics of the produced plants and starches are described.

  7. 20. Molecularly Imprinted Polymers at the Nanometric Scale: Synthetic Receptors for Chemical Sensors

    Författare :Anne-Sophie Belmont; Tillämpad biokemi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; biopolymers; Polymer technology; Biokemisk teknik; Biochemical technology; Nanostructures; Synthetic Receptors; Optical Sensors; Molecular Imprinting; Polymer; Polymerteknik;

    Sammanfattning : In this thesis, polymerisation techniques or deposition methods have been developed permitting the creation of thin molecularly imprinted polymer (MIP) films or patterns and their interfacing with transducer surfaces for biosensor applications. The creation of ultra thin films has been achieved using two different techniques, spin-coating and in-situ polymerization of thin films of monomers containing a sacrificial polymeric porogen, and autoassembly of MIP nanoparticles with the aid of an associative linear polymer.
