Abstract: A method for producing a fusion mixture for a transfer of a charged molecule into and/or through a lipid membrane is disclosed. In an embodiment, the method comprises: providing an initial mixture comprising a positively charged amphipathic molecule A, an aromatic molecule B with hydrophobic range and a neutral, amphipathic molecule C, whereby the molecule types are at hand in a ratio A:B:C of 1-2:0.02-1:0-1 mol/mol; generating a fusogenic liposome by absorption of the initial mixture in a watery solvent; providing a charged molecule; forming a complex from the charged molecule and a neutralizing agent; and incubating the complex with the fusogenic liposome so that a fusion mixture is obtained.

Abstract: The invention relates to a fusion mixture for the lipid-containing membrane modification of an arbitrary target membrane, a cell membrane, a constituent of a cell membrane or a cell membrane separated from remaining cell constituents, in vivo or in vitro, comprising a positively charged amphipathic molecule A and an aromatic molecule B, wherein the molecule of type A and the molecule of type B are present at a ratio A:B of 1:0:02 to 1:2 mol/mol.

Abstract: Disclosed is a mixture of amphipathic molecules and a method for modifying cells in vivo by way of membrane fusion with these molecules.

Abstract: The invention relates to a method for producing a structured elastomer. The invention is characterised in that the elastomer is applied and hardened directly on a structured SiO2-surface. As a result, highly-deformable, micro-structured elastomers can be produced for force sensors which are used during the characterisation of new therapeutic agents.
