Purpose of the Study:

• To investigate the supercritical foaming of composite polycaprolactone scaffolds.
• To evaluate the impact of graphene oxide (GO) and reduced graphene oxide (rGO) on scaffold properties.
• To assess the biocompatibility and cell interactions of the developed bone scaffolds.

Main Methods:

• Supercritical fluid foaming technique was employed for scaffold fabrication.
• Structural and mechanical properties of PCL/GO and PCL/rGO composite scaffolds were analyzed.
• Co-culturing and live/dead assays were performed to evaluate cell viability and behavior.

Main Results:

• The addition of GO and rGO influenced the foaming parameters and scaffold microstructure.
• Composite scaffolds exhibited desirable mechanical flexibility and endurance.
• Scaffolds demonstrated excellent biocompatibility, supporting cell proliferation and varied surface interactions.

Conclusions:
