Effect of degumming on FTIR spectra and β-sheet content of silk films. (A) The FTIR spectra for the amide I region are depicted along with an example FSD and the fitted Gaussian profiles. There were no discernable differences between the three FTIR spectra. (B) FTIR measurements and FSD analysis showed no difference (p>0.01, n=3) between the β-sheet content of the films formed from 5, 30, and 60 mb silk solutions. Error bars represent the standard deviation of the mean.
