A method of surface treatment of at least part of a surface of an article, said method comprising:
- electrochemical deposition of a layer containing calcium and phosphorus ions onto an electrically conductive substrate;
- and
- incorporation of a therapeutic agent into said electrochemically deposited layer.
An article comprising:
- on at least part of an electrically conductive substrate an electrochemically deposited layer containing calcium and phosphorus ions, wherein a therapeutic agent is incorporated within said electrochemically deposited layer.
An article comprising:
- an outer coating of calcium and phosphorus containing crystals on an electrically conductive substrate;
- and
- a therapeutic agent incorporated within and/or between said crystals.
