【 摘 要 】

Pulse laser ablation of solids in liquids (PLAL) technique has been used to obtain Hydroxyapatite (HAp) suspensions nanoparticles from catfish bone. Catfish bone was used as natural source to prepare two targets at different calcination, sintering and pressing conditions. These targets were different in crystallinity, crystallite size and lattice parameters. All deposited HAp layers composed from HAp nanoparticles at range (20 -100) nm as SEM images showed. The size of HAp nanoparticle depended on target's preparation conditions and deposition technique. XRD test confirmed the production of pure HAp. In vitro test proved the bioactivity of all deposited samples.
