Bioactive Coatings andCombination Strategies

Many next- generation surfaces combinae multiple mechanisms. For example, a coating may release an contritic for examinate killing while also presenting a zwitterionic layer to resist long-term adhelion. Others contribute bone morphogenetic proteins (BMPs) or hydroksyapatite te to promote osteointegration alongside antimicrobial silver foshate glass. Such multifunctival coatings aim tam andeattis the inherent trade- off between killing bacteria and supporting seing.
