3D Porous poly(lactic acid)/regenerated cellulose composite scaffolds based on electrospun nanofibers for biomineralization

One of the serious challenges in bone tissue engineering is the construction of biomimetic scaffolds, which can bridge the gap between mechanical strength and porous structure requirements. Although electrospinning technology can be used to create nanofibrous networks with a structure of artificial extracellular matrix (ECM), the restricted shapes and pore sizes block its application. Herein, we combine technologies of freeze-drying and...
