| 摘要 |
The invention provides an implantable device coated with a layer of calcium phosphate and optionally one or more biologically active substances such as growth factors, lipis, (lipo)polysaccharides, hormones, proteins, antibiotics or cytostatics. The device can be obtained by a nanotechnology process comprising subjecting a substrate to a surface treatment until a surface roughness with an average peak distance (Ra value) between 10 and 1,000 nm and subjecting the roughened surface to precipitation of calcium phosphate from a solution containing calcium and phosphate ions with optional coprepitation of the biologically active substance.
