NOVELTY - Preparing hydroxyapatite nanowire comprises (i) mixing water-soluble calcium salt solution and the water-soluble phosphate solution, adding graphene oxide nanosheet under stirring state to obtain a mixed solution, where mol ratio of the water-soluble calcium salt to the water-soluble phosphate is 0.1-2.5:1, (ii) subjecting mixed solution for microwave synthesis reaction, and (iii) centrifuging mixture to obtain a precipitate i.e. hydroxyapatite nanowire. USE - The method is useful for preparing hydroxyapatite nanowire. ADVANTAGE - The method: is simple and suitable for mass production; and consumes less energy. The hydroxyapatite nanowire has regular shape which is adjustable.
