The present invention provides, among other things, multilayer film coating compositions, coated substrates and methods thereof. In some embodiments, a structure includes a first and second layer-by-layer film disposes on a substrate, the structure being characterized in that layer-by-layer removal of at least the second film releases at least one polypeptide, and also may permit release of ions from the ceramic material so that a synergetic effect of the osteoinduction and osteoconduction of the structure is achieved.
