More and more applications of nanomaterials have been achieved in the biomedicine field. Numerous nanomedical devices, such as bone grafts with nano-hydroxyapatite and the silver-based anti-bacteria products, have been developed and have been trying to enter into the Chinese market. The State Food and Drug Administration of China (SFDA) is facing a critical challenge of how to explore and super...

Inorganic sulphate and silicate is required by all mammalian cells to function properly, it the most abundant anion in human plasma. Sulphate ions are major source of sulphur which considered an important element for sustenance life as present essential amino properly.This paper aimed compare constitutional physical property pure hydroxyapatite (HA) doped with different kinds anions such (SO42-...

Abstract Zinc and its alloys have been given promising consideration as a new biodegradable implant for use in the human body. Compact uniform nano hydroxyapatite coatings containing chitosan were successfully deposited onto zinc substrate an aqueous solution utilizing microwave-assisted process about 10 min. The quick composite are derived by microwave heating compared with electrodeposition. ...

Using bioactive and biocompatible coatings to biofunctionalized metallic implant surfaces for enhanced bone regeneration while resisting bacterial infection has attracted materials scientists' interest. Bio-metallic Ti-25Zr disc sample was prepared using powder metallurgy then coated an electrospinning method form a nanocomposite fiber as coating layer over the surface of metal alloy substrate....
