Illustrate the infrared spectra (FTIR) obtained for LMW Chi-S (blue line) versus LMW Chi-C (black line) (panel A) and HMW Chi-S (blue line) versus HMW Chi-C (black line) (panel B) using a ATR/FT-IR interspec 200-X spectrometer. Blue arrows show specific absorption bands at 815, 999 and 1218 cm−1 corresponding to the C–O–S and O=S=O. LMW Chi-C, low molecular weight commercial chitosan; LMW Chi-S, low molecular weight sulfated chitosan; HMW Chi-S, high molecular weight sulfated chitosan
