Preliminary characterization of nanoHA-Bubuk Wangi rice starch tissue scaffold

Scaffolds is an artificial bone implant to assist the regeneration of natural bone formation. Starch is a common polymer used to fabricate the scaffold. Generally, starch exhibits various properties corresponding to its botanical origin, granules size and structure. In Malaysia, different type and origin of soil may produce different properties of crops especially rice. Bubuk Wangi is a rice variant planted originally in Sarawak, Malaysia. This study is to fabricate the scaffold based on Bubuk Wangi rice starch and hydroxyapatite via solvent casting and salt leaching. From this research, the porosity, density, and morphology showed a good versatility in comparison with natural bone. As a conclusion, nanoHydroxyapatite combined with Bubuk Wangi rice starch has is a potential biomaterial to develop bone tissue scaffold.
