Lithium doped silica nanospheres/poly(dopamine) composite coating on polyetheretherketone to stimulate cell responses, improve bone formation and osseointegration

Lithium doping silica nanospheres (LSNs) and poly (dopamine) (PDA) composite were coated on polyetheretherketone (PK) surface (LPPK). Cytocompability, osteogenesis and osteointegration of LPPK were significantly improved by the coating.304
