Bioactive Coatings

The science behind the research

Due to its excellent biocompatible properties hydroxyapatite can be integrated into dental implants, bioactive surface for bone growth of human body, and biomedical implants.

Ongoing research

In our group, non-vacuum vapour depositions methods was used to deposit HA coatings in conjugation with poly (lactic acid). Preliminary tests showed adherence of human intestinal cells to PDLLA films confirming their viability for biomedical applications.
Nanocomposite coatings of HA/PDLLA were used as cost-effective scaffolds as osteoconductive coatings for bone and osteochondral repair.
