Figure 1

(a) Collagen sponge (A) and nano-β-TCP/collagen scaffold (B). (b) Surgical procedure: the samples were placed on the cranial bone. (c) Measurement of particle size distribution analysis for nano-TCP. (d) SEM micrograph of the β-TCP particles. (e) SEM micrograph of the nanopulverized β-TCP particles. Scale bars represent 5 mm (a), 10 mm (b), 10 μm (d), and 1 μm (e).
