After reaction with NHS-PEG-MAL, the peak area at the binding energy of 286.4 eV increases (Figure 1c and Table 2), and a new peak at the binding energy of 532.7 eV appears (Figure 2c and Table 2) because the introduced PEG chains contain abundant C-O bonds. In the C1s spectrum, the peak area at the binding energy of 286.4 eV keeps increasing after the covalent binding of RGD-containing peptides because of the contribution of C-N and C-O bonds in the peptides (Figure 1d and Table 2). In the O1s spectrum, the peak areas at the binding energy of 531.3 eV increase significantly (Figure 2d and Table 2) because the grafted RGD-containing peptides contain abundant N-CdO bonds. Taken together, XPS results of different PHBV films indicate the successful binding of RGD-containing peptides to ammonia plasma-treated PHBV surfaces through the cross-linker of bifunctional PEG. |

| 與NHS-PEG-MAL反應(yīng)之后,于鍵能286.4 eV處的峰面積增大(圖1c和表2),并且鍵能532.7 eV處出現(xiàn)一個(gè)新峰值(圖2c和表2),這是因?yàn)橐氲腜EG鏈帶有充足的C - O鍵。 在C1譜圖中, 286.4 eV鍵能處的峰面積在含有RGD縮氨酸的共價(jià)鍵合之后由于縮氨酸中的C - N和C - O鍵的作用而保持持續(xù)增加(圖1d和表2)。在O1譜圖中,于531.3 eV鍵能處的峰面積顯著地增大(圖2d和表2)這是因?yàn)榻又Φ膸в蠷GD的縮氨酸含有充足的N - CdO鍵。綜合來看,不同PHBV膜的XPS測(cè)定結(jié)果表明含有RGD的縮氨酸通過雙官能PEG的交聯(lián)劑與氨等離子體處理過的PHBV表面進(jìn)行了成功的結(jié)合。 |
