Figure 5

ATR-FTIR spectra of PHBHHx and SF/PHBHHx porous scaffolds. (a) PHBHHx porous scaffold; (b)–(e) SF-modified PHBHHx porous scaffolds flushed with PBS solution (pH = 7.4) at 37°C for 0, 7, 14, and 21 days, respectively. The flush rate was 55 mL/min which was the blood impulse rate under normal physiological condition [20].
