Scaffold characterization. A Comparison of the FTIR spectra of pure PCP and crosslinked PCP-br (a amide A, b amide B, c amide I, d amide II, e amide III, f carbohydrate region). B Gross observation of PCP-br by CX process (1′CX: pre-crosslinking, 2′CX: post-crosslinking). C Mechanical strength of PCP-br by CX process. D Wettability of PLGA-br, PCP-br, and PCP-sp
