Claim 0:
1. An alkaline composition for etching a nanoscale surface geometry on a metal surface of a body implantable device, the composition comprising:
a metal hydroxide; one or more chelating agents; and component metals of the metal surface, wherein the component metals of the metal surface comprise titanium at 0.1 ppm to 10,000 ppm, and
wherein the body implantable device is a bone-contacting device and the nanoscale surface geometry enhances osseointegration when the bone-contacting device is implanted adjacent bone, or
wherein the body implantable device is a tissue-contacting device and the nanoscale surface geometry enhances endothelial attachment and proliferation when the tissue-contacting device is implanted adjacent tissue.
