Characterization of calcium phosphate coating and zinc incorporation on the porous alumina scaffolds

A porous ceramic alumina scaffold with compressive strength of 3.3 MPa was developed by a replication method using the network structure of cellular polymer foam. The biocompatibility of ceramics based on Al2O3 required further improvement to provide strong bonding to natural bone tissue. To address...

Description
Summary:A porous ceramic alumina scaffold with compressive strength of 3.3 MPa was developed by a replication method using the network structure of cellular polymer foam. The biocompatibility of ceramics based on Al2O3 required further improvement to provide strong bonding to natural bone tissue. To address the problem of the interface between alumina and bone, a novel calcium phosphate was developed with Zn2+ (CaP-Zn) coating onto porous alumina ceramic scaffold by impregnating with calcium phosphate/poly(vinyl alcohol) slurry. The tri-dimensional alumina scaffold coated with CaP-Zn was characterised by SEM, EDS and FTIR. 17 refs.
