Abstract

Purpose

The present study was focused on the synthesis and characterization of cerium with hydroxyapatite for biomedical applications.

Method

Hydroxyapatite (HAp) substituted with variable concentration (0.075, 0.150, 0.225%) of cerium (Ce) was synthesized by sol–gel method. The structural and morphological properties were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM) and energy-dispersive X-ray analysis (EDAX). The average crystallite size of the synthesized samples was determined as 20 nm. The functional group has been identified by FTIR. Antibacterial and anti-inflammatory focused the antibacterial activity and albumin denaturation of cerium. Blood compatibility was performed by hemolytic assay.

Result

The structural property was characterized by X-ray diffraction and crystallite size was determined as 20 nm. The FTIR spectra confirmed the presence of hydroxyl and phosphate functional groups. Antibacterial studies revealed that all cerium-doped hydroxyapatite samples exhibit good antibacterial activity against the pathogens Streptococcus oralis and Streptococcus pyogenes. Hemolysis ratios of the cerium-doped hydroxyapatite sample indicate good blood compatibility. Anti-inflammatory results exhibit high inhibition percentage of albumin denaturation for cerium-doped hydroxyapatite samples.

Conclusion

This study suggests that the cerium proves that it is a good material for biomedical applications.
