Synthesis and Characterization of a New Collagen-Alginate Aerogel for Tissue Engineering

Figure 7

FTIR spectra of collagen-alginate-GO aerogel. The spectra show peaks at 1209 cm^-1, 1551 cm^-1, and 1662 cm^-1 that correspond to amide band peaks of collagen and peaks at 1240 cm^-1, 1340 cm^-1, 1408 cm^-1, and 3418 cm^-1 related to functional groups of GO.
