(a) Digital photographs of dc-ngCA-silk hydrogel (top) and agarose gel (bottom) under room light (left) and UV illumination (right). (b) FTIR absorbance spectra in the amide I region versus wavenumber for the dc-ngCA-silk and sc-ngCA-silk hydrogels. The medium–medium line marks the center of the absorbance band at 1630 cm−1 that corresponds to β-sheets.
