Surface modification of polymers (e.g. polyolefin) is a straightforward strategy to render anti-adherence quality which deters the susceptibility to bacterial

adhesion. This can be achieved by deposition of thin antibacterial

layers tethered to the surface of polymeric support already

chemically grafted with a spacer of a brush-like pattern. This

multistep approach has aroused great interest thanks to several

advantages such as convenient and controllable introduction of

biocidal species with a high surface density together with precise

localization and long stability of the grafted layers.
