A wide variety of different biomaterials are currently employed in medical applications throughout the world.Research towards the development of new biomaterials has traditionallyfocusedonthepreparationoffunctionalmateri- alscapableofthesimpleadhesionofcellsortheconnectionof tissues to metals and ceramics. However, there is a growing interest in the development of biomaterials involving the immobilization of growth factors, which would allow these artificial materials to regulate specific cellular functions, including the gene expression processes associated withcell growth and differentiation.[1]Although numerous studies havebeenreportedpertainingtotheuseofmetallicmaterials inmedicaldevicessuchasartificialjoints,dentalimplants and stents, there have been very few reports concerning the surface modification of metal or ceramic materials with biological agents.
