Abstract

The present invention relates to a biodegradable multilayer nanocapsule for the delivery of at least one biologically active agent into at least one target cell consisting of at least two layers of at least two biodegradable polymers which are laid one onto the other and whereby the biologically active agent is layered onto a layer of a biodegradable polymer and covered with a further layer of a biodegradable polymer, whereby one biologically active agent is a nucleic acid.
