Calcium phosphate nanowires could be obtained in the reverse microemulsions of nonionic surfactant and ionic surfactant. Amorphous calcium phosphate nanowires with 325 nm in length and 13 nm in width could be prepared in water/ C12E8(polyethylene glycol alkyl ethers)/cyclohexane system while well-crystallized calcium phosphate with 500 nm in length and 14 nm in width could be prepared in the system of water/CTAB(cetyltrimethy lammonium bromide)/cyclohexane. However
the mechanism of the growth of crystal in these two kinds of system was entirely different.C12E8 in reverse microemlusion played a role of “microreactor”.With the assistance of CTAB
well-crystallized calcium phosphate nanowires could be obtained
in which surfactant CTAB acted as guiding the growth direction
