Auto-Cross-Linking Hydrogels of Hydrogen Peroxide-Oxidized Pectin and Gelatin for Applications in Controlled Drug Delivery

Figure 9

FTIR spectra of hydrogels. Absorbance is a wavelength function. The spectra shown in Figure 8 are (a) H.6.20 (6% HOP and 20% of gelatin), (b) L.6.20 (6% LOP and 20% of gelatin), (c) N.6.20 (6% NOP and 20% of gelatin), (d) 0.20 solely gelatin (20% gelatin), and (e) solely native pectin.
