Whey-Derived Porous Carbon Scaffolds for Bone Tissue Engineering

Biomedicines. 2021 Aug 26;9(9):1091. doi: 10.3390/biomedicines9091091.

ABSTRACT

Porous carbon structures derived from whey powders are described and evaluated as potential scaffolds in bone tissue engineering. These materials have a porosity between 48% and 58%, with a hierarchical pore size distribution ranging from 1 to 400 micrometres. Compressive strength and elastic modulus are outstanding for such a porous material, being up to three times better than those of traditional HA or TCP scaffolds with similar porosities. They also present non-cytotoxic and bioactive behavior, due to their carbon-based composition that also includes some residual mineral salts content.
