Osteoconductivity and Biodegradability of Collagen Scaffold Coated with Nano-β-TCP and Fibroblast Growth Factor 2
Figure 3
(a) SEM micrograph of the nano-β-TCP/collagen scaffold. (b) SEM micrograph on the inner surface of the nano-β-TCP/collagen scaffold. (c) Higher magnification of the nano-β-TCP/collagen scaffold. Dispersed β-TCP particles attached to fibers of collagen sponge. (d) Higher magnification of the nano-β-TCP/collagen scaffold. Aggregated forms of nano β-TCP particles are partly exhibited (arrow). (e) TEM micrograph of nano-β-TCP/collagen scaffold. Nano β-TCP particles are distinctly recognized (arrows). (f) XRD patterns of β-TCP (A) and nano-β-TCP/collagen scaffold (B). Abbreviations: Col, collagen sponge. Scale bars represent 100 μm ((a), (b)), 10 μm (c), 200 nm (d), and 100 nm (e).
