Abstract

Significant advances have been made in the technology of biomedical coatings and materials. This talk will provide an extensive review of coating types and surface modifications for biomedical applications. In many cases, side by side with traditional properties, like wear and corrosion resistance, biomaterials have to be compatible with body tissues and fluids, have anti-microbial activity and, in specific cases, contributing for a good integration of the material in the human body (e.g. osseointegration). It is difficult to find a unique material with all these functionalities, reinforcing the importance of surface engineering to supply new functionalities. The topic of this talk is centred in the surface modification of materials, traditionally used for biomedical applications, in order to improve their performance for specific cases. Different surface modification methods will be presented and the potential applications like orthopaedic (Figure 1), cardiovascular and urethral stents (Figure 2), biosensors (Figure 3), dental implants (Figure 4) will be discussed. Several cases studies from antimicrobial coatings to bioactive surfaces will be presented.
