Mechanical properties of scaffolds. Scaffolds were fabricated with EtOH–NaOH-treated porous PLGA microspheres for 6 h and 24 h at 37 °C, 40 °C and 50 °C. (A) Representative stress–strain graphs obtained during compression after 24 h at 37 °C. (B) Compressive strength of scaffolds sintered at 37 °C, 40 °C and 50 °C (values taken at 20% strain). (C) Young’s modulus values for scaffolds sintered at 37 °C, 40 °C and 50 °C.
