Hydroxyapatite-chitosan hybrid nano-materials

Self-assembled nano-materials are currently an area of research with high throughput due to the opportunities it provides to fields ranging from semiconductor engineering to gene delivery. There is also considerable interest in nano-particulate systems that attain a lower energy state by self-assembly through favorable and repeated surface interactions as they mimic those commonly found in natural biological systems. This work presents a simple route to first synthesise a highly stable suspension of nano-hydroxyapatite (similar to 40nm) with chitosan and subsequently self-assemble the suspended nano-hydroxyapatite particulates onto a substrate.
