Caption : fig. s1: characterization of the progression of mineralization in i-dc gels. sem micrographs of neat i-dc (a), i-dc ss40% (b), and i-dc 60% (c) gels, as-made (i), and at days 3 (ii), 7 (iii) and 14 (iv) in sbf. particle deposition was detected on all i-dc ss gels from days 3 to 14 in sbf.

File Name : fig. s2.tiff

Caption : fig. s2: structural characterization of mineralized i-dc gels. atr-ftir spectra of neat i-dc, i-dc ss20%, i-dc ss 40% and i-dc 60% gels up to day 14 in sbf. there was an increase in the absorption bands associated with both phosphate and carbonate groups in i-dc ss40% gel as a function of time in sbf, respectively. there were no changes in the absorption bands of i-dc ss60% gels between days 7 and 14 in sbf.

Caption : fig. s3: structural analysis of acellular gels in osteogenic medium. atr-ftir spectra of acellular neat i-dc (left) and i-dc ss40% (right) gels, as made and at days 14 and 21 in osteogenic medium. there were no changes to the spectra as a function of time.
