One‐pot porogen free method fabricated porous microsphere‐aggregated 3D PCL scaffolds for bone tissue engineering

Three-dimensional (3D) scaffolds with interconnected, hierarchically structured pores, and biomimetic nanostructures are desirable for tissue engineering, where preparation with a facile and biocompatible strategy remains challenging. In the present work, an innovative porous microspheres-aggregated 3D PCL scaffold with macropores, micropores, and nanofibrous-like structures was fabricated through a one-pot thermally induced phase separation...
