  2. 1. Condensation of DNA for Gene Delivery: Studies on Vector-Nucleic Acid Interactions and Transfection Efficiency

    Author : Kristina Fant; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; dendrimer; endocytosis; uptake; gene delivery; optical spectroscopy; structure-activity relationship; DNA; cell-penetrating peptide;

    Abstract : This thesis concerns the delivery of nucleic acids into cells and tissues with the aim to change or correct gene expression. The field of gene delivery has the ultimate goal of producing genetic drugs for clinical applications, and the activity in this area is intense although so far the use is limited to research purposes.

    Abstract : Förfrågan efter nya och mer avancerade applikationer är en pågående process vilket leder till en konstant utveckling av nya material. För att förstå relationen mellan en applikations egenskaper och dess sammansättning krävs full förståelse och kontroll över materialets uppbyggnad. READ MORE

  6. 4. Controlling DNA compaction and the interaction with model biomembranes

    Author : Marie-Louise Ainalem; Fysikalisk kemi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; model biomembrane; DNA compaction; cryo-TEM; null ellipsometry; dynamic light scattering; toroid; bilayer; neutron reflectivity; dendrimer; PAMAM; DNA; poly amido amine ;

    Abstract : The studies described in this thesis forms part of a larger collaborative project, Neonuclei, with the objective to design a module for packaging the negatively charged DNA into a ”neonucleus” with transcription competence. There are many applications that require control of DNA compaction, i.e. packaging or condensation. READ MORE
