The protein adsorption on the polymer surface. The protein adsorption on the polymer surface: (a) FITC-BSA distribution on the surface of PHB, PHB-HV, PHB-PEG, and PLA polymer films visualized by florescence microscopy; (b) the absorption of proteins from bovine fetal serum on the PLA, PHB, PHB-HV and PHB-PEG polymer films. Data were shown as Mean ± SD (n = 6); * vs PLA, # vs PHB, p < 0.01.
