  1. 1. Dendrimer-mediated gene delivery: Effect of polymer structure on cellular response

    Author : Kristina Fant; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; gene therapy; DNA condensation; cationic polymers; toxicity; non-viral vector; drug delivery; polyplex; PAMAM dendrimers;

    Abstract : The delivery of nucleic acids to cells, in vitro and in vivo, is becoming a realistic approach for intervention with gene expression at a molecular level. It can be used to repair malfunctioning genes or to introduce new functionalities, with the most important application being clinical treatment of human diseases. READ MORE

    Abstract : Catalytic systems are one of the most effective technologies of modern chemical processes. The system uses a molecule called ‘catalyst’ that is capable of catalyzing a reaction without being produced or consumed during the process. READ MORE

  3. 3. Nanostructured surfaces created by the interactions of dendrimers and oppositely charged amphiphiles

    Author : Marianna Yanez; Fysikalisk kemi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; PAMAM; Surfactant; SDS; Lipid; Bilayer; Model Biomembrane; Nucleolipid; DLPA; DLPU; DNA; RNA; Neutron Reflectometry; Poly amidoamine ; Interface; Adsorption; Polyelectrolyte;

    Abstract : The research described in this thesis aims to understand the interactions between cationic poly(amidoamine) (PAMAM) dendrimers and small oppositely charged amphiphiles at the solid-liquid and air-liquid interfaces in relation to the bulk solution behavior. There is high interest in PAMAM dendrimers because they are well-defined polymers with a hierarchical architecture which makes them promising materials as nanocapsules and gene vectors. READ MORE

  4. 4. Enhancing the efficiency of viral and non-viral gene delivery vectors

    Author : Safa Bazaz; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Gene therapy, which involves the introduction, alteration, or deletion of genetic material within cells to treat or prevent disease, holds great promise for addressing various genetic disorders and other medical conditions. However, several challenges remain in the field, particularly concerning nucleic acid delivery into target cells. READ MORE

  5. 5. Liquid crystalline polymers for nonlinear optics : pyroelectric polymers and ferroelectric dendrimers

    Author : Jonas Örtegren; KTH; []
    Keywords : ;

    Abstract : This thesis deals with liquid crystalline materialsincluding monomers, side-chain polymers, crosslinked polymers,and dendrimers. The materials are pyroelectric, meaning thatthere is a macroscopic electric polarization in the material,which is energetically stable in the absence of externalfields. READ MORE
