  • Biomimetic hydroxyapatite synthesis
    Patent number: 8287914
    Abstract: A method for preparing nanoscale hydroxyapatite particles by combining an amount of a calcium ion source, which includes calcium acetate, and an amount of a phosphate ion source, wherein the amounts are sufficient to produce nanoscale hydroxyapatite particles and the amounts are combined under ambient conditions to produce the hydroxyapatite particles. Nanoscale hydroxyapatite particles are also presented.
