Bacterial infection of chronic wounds is a major healthcare problem that affects the quality of life of millions of patients worldwide and leads to a substantial healthcare cost burden. This project focused on the manufacture of a potential wound healing agent. Plasma polymers from oregano secondary metabolites (PP-OSMs) were fabricated by radiofrequency plasma-enhanced chemical vapor deposition (RF-PECVD) in continuous and pulse plasma modes at room temperature. The surface, biocompatibility, and antibacterial properties of the PP-OSMs were investigated. Polymers fabricated by RF-PECVD retained the functional groups of OSMs, promoted human dermal fibroblast adhesion, inhibited Staphylococcus aureus attachment, and eliminated Pseudomonas aeruginosa. The PP-OSM coatings are potential candidates for use in medical applications where cell biocompatibility and antibacterial properties are required.
