Item Self-assembled right handed helical ribbons of the bone mineral hydroxyapatite(JOURNAL OF MATERIALS SCIENCE-MATERIALS IN MEDICINE, 2009) Suganthi, RV; Girija, EK; Kalkura, SN; Varma, HK; Rajaram, AA self-assembled right handed helical ribbon of bone mineral, hydroxyapatite (HAp) was crystallized in sodium meta silicate gel matrix at 27A degrees C and the physiological pH (7.4). At temperatures 37 and 47A degrees C, helical structures were followed by many Liesegang rings. The samples were characterized by FT-IR, XRD, SEM, ICP-OES and TG-DTA techniques. The helical ribbon consisted of platy Ca-deficient apatite crystals of size 2.8 mu m. Liesegang ring had a continuous network of fibers with interconnected pores. The samples exhibited bioactivity when soaked in SBF.
