Solvothermal synthesis of submillimeter ultralong hydroxyapatite nanowires using a calcium oleate precursor in a series of monohydroxy alcohols

Hydroxyapatite (Ca10(OH)2(PO4)6, HAP), as the major inorganic component of bones and teeth in vertebrates, is a very important biomaterial with high biocompatibility, nontoxicity and high thermal stability, thus, it has wide applications in various biomedical fields. Among various morphologies of HAP, HAP nanowires are very promising for various applications; however, the synthesis of ultralong HAP nanowires with lengths larger than 100 μm is...
