We present the utilization of gaseous carbon dioxide (CO2) with increased mineralization rate in the presence of dopamine, a biomimetic molecule of adhesive foot protein secreted from mussels, to synthesize hollow calcium carbonate (CaCO3) microspheres and their composites with biodegradable polymer fibers. This CO2-consuming route was applied to the development of highly porous electrospun polycaprolactone scaffold hybridized with CaCO3 vaterite crystals that were readily transformed to bone hydroxyapatite minerals in a simulated body fluid.
