Control of bisphosphonate release using hydroxyapatite granules.
The efficacy of hydroxyapatite (HAp) as a carrier was investigated to establish a method of local administration of bisphosphonates (Bps), which has currently been administered systemically. HAp granules (300-500 microm in size) with different physicochemical features were prepared by altering the sintering temperature. To ascertain the physicochemical properties of the HAp granules, their crys...
متن کاملSynthesis and Characterization of Hydroxyapatite Nanocrystals via Chemical Precipitation Technique
In this study, hydroxyapatite (HA) nanocrystals have been synthesized via chemical precipitation technique. Diammonium hydrogen phosphate and calcium nitrate 4-hydrate were used as starting materials and sodium hydroxide solution was used as the agent for pH adjustment. The powder sample was evaluated by techniques such as scanning electron microscope, transmission electron microscope, Fou...

متن کاملInitial Adhesion Behavior of Fibroblasts onto Hydroxyapatite Nanocrystals
The initial adhesion, spreading and cytoskeleton changes of fibroblast NIH3T3 cells onto hydroxyapatite (HAp) and oxidized poly(styrene) (PSox) sensors preadsorbed fetal bovine serum were analyzed by using a quartz crystal microbalance with dissipation technique and an atomic force microscopy (AFM). The frequency shift (Δf ) and the dissipation shift (ΔD) curves on HAp nanocrystals showed the d...
