  1. 1. Statistical Mechanical Studies of Titrating Polyelectrolytes

    Författare :Magnus Ullner; Kemiska institutionen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; integral equation theory; variational calculations; Monte Carlo simulations; end-to-end separation; apparent dissociation constant; titrating polyelectrolytes; electrostatic interactions; Physical chemistry; Fysikalisk kemi;

    Sammanfattning : Different models and statistical mechanical approximations for titrating polyelectrolytes are studied and the results compared with Monte Carlo simulations and experimental data. Three types of models have been used in the simulations: i) rigid structures and freely jointed chains with ii) rigid bonds and iii) flexible, harmonic bonds. LÄS MER

  3. 2. Carbohydrate-Functionalized Nanomaterials : Synthesis, Characterization and Biorecognition Studies

    Författare :Na Kong; Mingdi Yan; Joseph J. Barchi Jr; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; carbohydrate; glyconanomaterials; perfluorophenyl azide PFPA ; CuAAC; AAAC; coupling chemistry; 19 F q NMR; lectin; carbon nanomaterials; microwave irradiation; Kemi; Chemistry; Bioteknologi; Biotechnology;

    Sammanfattning : This thesis focuses on the development of carbohydrate coupling chemistry on nanomaterials and their biological activity studies. It is divided into two parts:In part one, two carbohydrate immobilization approaches, based on perfluorophenyl azide (PFPA)-functionalized silica nanoparticles (SNPs), are presented, where the binding affinity of the glyconanoparticles was evaluated through carbohydrate-lectin interaction.

  4. 3. Reaction-Diffusion kinetics of Protein DNA Interactions

    Författare :Anel Mahmutovic; Johan Elf; David van der Spoel; Pieter Rein ten Wolde; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; umbrella sampling; molecular dynamics; RDME; PDE; sliding; intersegment transfer; hopping; sterics; intersegment transfer; Biology with specialization in Molecular Biotechnology; Biologi med inriktning mot molekylär bioteknik;

    Sammanfattning : Transcription factors need to rapidly find one specific binding site among millions of nonspecific sites on the chromosomal DNA. In this thesis I use various aspects of reaction-diffusion theory to investigate the interaction between proteins and DNA and to explain the searching, finding and binding to specific operator sites.
