Synthesis and Characterization of Hydroxyapatite/Graphene Oxide for Biomedical Applications

The well resemblance of the mineral phase of human hard tissue and excellant bioactivity of Hydroxyapatite makes it as an essential candidate in biomedical field, especially in orthopedics. The utility of composites of hydroxyapatite is tremendous in hard tissue implants as the properties can be tailored to meet specific physical, chemical and biological needs. In this study, Hydroxyapatite/Graphene oxide composite (HA/GO) was synthesized by co-precipitation method and Graphene Oxide was prepared by a modified Hummers’ method.The samples were subjected to XRD, FTIR, SEM and Raman analyses. SEM images revealed crumpled morphology and exfoliated form of GO. And also FTIR analysis confirmed HA/GO composite formation. Antibacterial studies were carried out using Enterococcus faecalis (gram positive) and Pseudomonas aeruginosa (gram negative). The antimicrobial test revealed that the composite inhibited both Gram positive and negative bacteria.
