Citrate Concentration in Bone Structure (image) DOE/Ames Laboratory Share Print E-Mail Caption This diagram shows the effect of citrate concentration on the size of hydroxyapatite crystals fabricated with self-assembling block copolymer templates. Just as it does with actual bone structure, as the concentration of citrate increases, the thickness of the nanocrystals decreases and the thinner nanocrystals appear to make the bone more resistant to stress cracking.
