Surface modification of biomaterials for biofilm control

Abstract

Amongst various methods to attain sound antibacterial and antifouling properties, surface modification of biomaterials combines efficiency, processing flexibility, and most importantly, the ability to preserve favourable bulk properties, such as mechanical strength and chemical inertness. This chapter will first briefly discuss key parameters by which the biomaterial surface can be described, namely surface chemistry and morphology, and their individual and combined contributions to cell-surface interactions. More emphasis will be placed on surface morphology as the area of much debate. The chapter will then describe a range of available methodologies for surface modification, with plasma-assisted modification as one of the foci.
