- •
Annealing of Pd nanolayers on PEN resulted to Pd aggregation and formation of discrete nanoislands.
- •
UV treatment was found as the gentlest sterilization method in term of physicochemical properties of Pd/PEN interface.
- •
Autoclaving and chemical sterilization by ethanol resulted into remarkable changes of Pd/PEN interface.
- •
Cytotoxicity of Pd samples was insignificant.
- •
Pd nanostructures are potentially applicable as health-unobjectionable antibacterial coatings of medical devices.
