Abstract
The present invention relates to a biocompatible cationic nanogel comprising a polymer network, said polymer network comprising polymer units interconnected with one another through a cross-linking agent, wherein said polymer network can be obtained by polymerizing N-vinylcaprolactam and a cross-linking agent in a dispersed medium, in the presence of a cationic initiator and a cationic or non-ionic emulsifier. The invention also relates to methods for obtaining the mentioned nanogels as well as to pharmaceutical compositions comprising them.
