Abstract
Bacterial infection and lack of osteoinductive ability are the major concerns of titanium-based bone implants. This chapter describes the construction of bio-functionalized ZnO coatings with both self-antibacterial and osteoinductive properties on titanium implants. To obtain ZnO-modified coatings with strong binding forces with substrates, two preparation methods are presented including atomic layer deposition and laser cladding techniques. Next, the antibacterial and osteoinductive properties of ZnO-based coatings are described including Ag/ZnO/hydroxyapatite-Ti, Ti-ZnO/polydopamine/arginine-glycine-aspartic acid-cysteine and poly(lactic-co-glycolic acid)/Ag/ZnO-Ti. We summarize the balancing strategies of reducing cytotoxicity of ZnO to bone cells and enhancing its toxicity towards bacteria.
