Well-crystallized and pure nHA (monodispersed Nano-rods) were prepared using MW inpresence of Ethylenediamineteraacetic acid (EDTA),as the capping agent,in less than 3 min (Fig. 6). In accordance, well-crystallized HA Nano-strips were synthesized using MW and Cetyl-Trimethyl-Ammonium bromide (CTAB) as a nucleation and growth controlling agent [85].
