(A) Temporal change in scaffold weight with removal of PVA by washing in dH₂O (N = 4). Mechanical compression data of washed and unwashed scaffolds showing (B) deformation behavior and (C) compressive modulus between 8 and 10% strain (N = 5). SEM images of (D) washed and (E) unwashed LayFomm scaffolds, showing the appearance of micropores (arrowheads) following removal of PVA by washing in dH₂O. Error bars (A,C) and fill between lines (B) indicates standard deviation. For (A), lines are as follows: wet—smoothing spline, 7 knots; dry and Δ weight—non-linear fit, R² = 0.9907 and 0.9892, respectively. ****P < 0.0001.
