(a,b) Low and high magnification scanning electron microscopy (SEM) images of a decellularized sheet of collagen fibrils from bovine tendon prior to mineralization. (c,d) Low and high magnification SEM images of a similar collagen sheet after mineralization via 10 cycles of alternate soaking with both pAsp and citrate additives. Individual collagen fibrils are covered in plate‐like crystals, with larger spherical clusters of mineral frequently occurring. Unlike the sheets shown in Figure 3, the sheets shown here are unetched
