Abstract |
AB |
[EN] The invention relates to a wound dressing comprising at least the following components:a substrate, a layer of a biocompatible polymer film provided on said substrate, wherein said biocompatible polymer film is electro-conductive and capable to scavenge reactive oxygen species, and one or more therapeutic agents adhering to or incorporated into said layer of a biocompatible polymer film.In one preferred embodiment, said biocompatible polymer is a polydopamine/polypyrrol copolymer.A further aspect of the invention relates to methods for preparing such a wound dressing.In one specific embodiment, a method for preparing said wound dressing comprises at least the following steps:a) preparing a biocompatible polymer film, which biocompatible polymer film is electro-conductive and capable to scavenge reactive oxygen species, by electropolymerisation on a conductive primary substrate;b) transferring the biocompatible polymer film prepared in step a) onto a non-conductive substrate;c) contacting the biocompatible polymer film or the composite material obtained in step a) or step b) with one or more therapeutic agents and immobilizing said therapeutic agent(s) to the polymer film or incorporating said therapeutic agent(s) into the layer of biocompatible polymer film provided on a substrate by means of covalent or non-covalent interactions between said therapeutic agent(s) and said biocompatible polymer film.In an alternative embodiment, the biocompatible polymer film is prepared directly on a non-conductive substrate. |
