1. A nanostructure (20) made of a plurality of nanocrystals on at least one surface (39) or surface region of a titanium body (10),
wherein the nanocrystals (40) have a tetragonal-pyramidal basic shape, at least in some regions,
wherein an area density of the nanocrystals (40) per μm2 is between 40 and 400, wherein the area density decreases with increasing crystal size, and
wherein an average spacing between adjacent nanocrystals (40) at a height of 23 to 100 nm is 50 to 160 nm.
