Glutamic Acid-mediated Synthesis of Ultralong Hydroxyapatite Nanoribbons under Hydrothermal Conditions

A facile hydrothermal preparation of hydroxyapatite nanoribbons was successfully established by adding glutamic acid as the modulator. The resultant nanoribbons are elongated along [0001] direction with ≈70 nm in thickness and ≈500 nm in width. The adsorption of glutamate ions on the crystal surfaces led to the formation of uniform ribbon-like morphology.
