3D-printed photoluminescent bioactive scaffolds with biomimetic elastomeric surface for enhanced bone tissue engineering

Three dimensional (3D) printed porous bioactive glass nanoparticles scaffolds (BGNS) exhibit excellent bone integration and bone regeneration capacities, but the early rapid ion release, brittle mechanical properties and lack of functions limit their application. In this work, photoluminescent biomimetic elastomeric BGNS were fabricated by directly assembling poly(citrate-siloxane) (PCS) on the surface of BGNS (BGNS@PCS). The morphologies,...
