  2. 1. Concentrated DNA-amphiphiles Structure, Hydration, and Dynamics

    Author : Cecilia Leal; Fysikalisk kemi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; amphiphiles; DNA; Physical chemistry; diffusion NMR; solid-state NMR; electrostatics; dynamics; local order; Fysikalisk kemi; hydration;

    Abstract : The structure, hydration, and dynamics of concentrated DNA-amphiphile complexes were investigated by small-angle X-ray diffraction, sorption calorimetry, and nuclear magnetic resonance. A concentrated, electroneutral, DNA-amphiphile complex can be formed by mixing charge-stoichiometric solutions. READ MORE

  4. 2. Porphyrin Anchored DNA: Advances in DNA Nanotechnology

    Author : Jakob Woller; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : DNA nanotechnology has focused on the creation of complex structures using DNA as building blocks. DNA is an attractive construction material at the nano scale due to the self-assembly and specific base-pairing of the DNA bases, allowing the placement of functional groups with sub-nm precision.

  5. 3. Infrared spectroscopic studies : from small molecules to large

    Author : Nadejda Eremina; Andreas Barth; Silvia Maria Doglia; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Infrared spectroscopy; transcription factors; DNA; creatine kinase; CaATPase; water; ligand binding; biofarmaci; Biopharmaceutics;

    Abstract : Infrared light (IR) was first discovered by Friedrich Wilhelm Herschel in 1800. However, until 1940’s, molecular IR studies involved only water and small organic molecules, because of the long measurement times. READ MORE

  6. 4. Studies on Nucleic Acids – Structure and Dynamics

    Author : Johan Isaksson; Jyoti Chattopadhyaya; Douglas H. Turner; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Bioorganic chemistry; nucleic acids; modified nucleotides; NMR; structure; dangling-end; single-stranded; thermodynamics; hydration; Bioorganisk kemi; Bioorganic chemistry; Bioorganisk kemi;

    Abstract : This thesis is based on six papers, Papers I-VI, focusing on the interplay between the stabilizing elements of nucleic acids self-assembly; hydrogen bonding, stacking and solvent effects. In Paper I we investigate how the substitution of the O4' for CH2 in the sugar moiety of adenosine (2'-deoxyaristeromycin) at the A6 position of the Dickerson-Drew dodecamer makes the two modified bases exist in a dynamic equilibrium between Hoogsteen and Watson-Crick base pairing in the NMR time scale.

  7. 5. Nuclear Magnetic Relaxation Dispersion and Pulsed-Gradient Spin Echo Studies of Biomolecular Solutions and Amphiphilic Liquid Crystals

    Author : Haukur Jóhannesson; Biofysikalisk kemi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; stretched dispersion; DNA hydration; solvent dynamics; NMRD; Random flight simulation; PGSE; Diffusion; Nematic phase; NMR; Amphiphilic liquid crystals; Physical chemistry; Fysikalisk kemi;

    Abstract : Biomolecular solutions and amphiphilic liquid crystals are studied by Nuclear Magnetic Resonance Dispersion (NMRD) and Pulsed-Gradient Spin Echo (PGSE) respectively. A random-flight simulation is performed to obtain the obstructing factors for self-diffusion of small molecules in macrofluids. READ MORE
