The present invention relates to an antibacterial co-polymer comprising a water soluble backbone polymer having in at least one end a dendritic or hyperbranched polymer of generation 1 to 6 wherein at least one functional group comprising a carboxylic amine has been covalently attached to the periphery of the dendritic or hyperbranched polymer. The present invention also relates to said anti-bacterial co-polymer when said co-polymer has been cross-linked with a cross-linking agent and to uses of the cross-linked co-polymer in a hydrogel for the treatment or prevention of bacterial infections, particularly in surgical site infections (SSIs).

Hydrogel composition and its uses

The present invention pertains to antimicrobial compositions comprising inter alia at least one alkenyl- and/or alkynyl-substituted polysiloxane, at least one polysiloxane comprising silicon-bonded hydrogen atoms, and at least one hydrosilylation catalyst, as well as antimicrobial silicone gels, wound dressings, and methods of preparing the above.
