Abstract:
A three-dimensional smart polymer matrix is formed by a first epoxy chemical reaction linking a linear polymer chain and a branched polymer chain, wherein the polymer chains are flexible and one or more reactive molecule species remain unreacted, at a predetennined mathematical ratio of reacted to un-reacted molecules and molecule species, and the un-reacted molecular species are available for further chemical reaction, protonation or deprotonation after the first chemical reaction. The resulting smart polymer matrix is hydrophilic and non-soluble to a solvent or electrolyte.
Abstract:
Methods for forming a graft copolymer of a poly(vinylidene fluoride)-based polymer and at least one type of electrically conductive polymer, wherein the electrically conductive polymer is grafted on the poly(vinylidene fluoride)-based polymer are provided. The methods comprise a) irradiating a poly(vinylidene fluoride)-based polymer with a stream of electrically charged particles; b) forming a solution comprising the irradiated poly(vinylidene fluoride)-based polymer, an electrically conductive monomer and an acid in a suitable solvent; and c) adding an oxidant to the solution to form the graft copolymer. Graft copolymers of a poly(vinylidene fluoride)-based polymer and at least one type of electrically conductive polymer, wherein the electrically conductive polymer is grafted on the poly(vinylidene fluoride)-based polymer, nanocomposite materials comprising the graft copolymer, and multilayer capacitors comprising the nanocomposite material are also provided.

Abstract:
The invention relates to a method for carrying out the targeted transfection of cells, to compositions, which can be used for such methods, and to corresponding medicaments for use in gene therapy. The invention particularly relates to a method for introducing nucleic acid into cells involving the following steps: (a) mixing a nucleic acid with a dendrimer, whereby a portion of the dendrimer molecules is biotinylated; mixing the prepared complex, which consists of a nucleic acid and a dendrimer, with a second complex, which consists of an avidin or a streptavidin and of a biotinylated target-specific binding molecule, and; (c) incubating the complex prepared in step (b) with cells. Dendrimers that are well-suited for the invention are, for example, partially solvolyzed polyamidoamine (PAMAM) dendrimers. Target-specific binding molecules are, in particular, cell type-specific markers also of the cell surface of the target cells.
