1. A pro-biofilm coating applied on a substrate by means of cold atmospheric plasma polymerization of a precursor comprising carbon-oxygen groups, namely C—O, O—C═O, and C═O, which produce oxidative stress promoting creation of biofilm by bacteria, the coating having a roughness such that it promotes the creation of more than 100% biofilm on the substrate, where the 100% of biofilm is the one as produced on the same substrate being devoid of said pro-biofilm coating.
