Facile preparation of bioactive nanoparticle/poly(ε-caprolactone) hierarchical porous scaffolds via 3D printing of high internal phase Pickering emulsions

Bioactive and biocompatible scaffolds possessing hierarchical porous structures and tunable multi-functional performance have attracted increasing interest in the biomedical field, especially in bone tissue engineering. In this work, we report a convenient and effective approach to construct bioactive nanoparticle/poly(ε-caprolactone) (BNPCL) scaffolds with hierarchical porous structures based on solvent evaporation of 3D printed water-in-oil...
