ATR-FTIR spectra of the a PCL-g-P(GMA)1 from 1 h of ATRP, b PCL-g-P(GMA)2 from 3 h of ATRP, c PCL-g-P(GMA)1-c-gelatin, and d PCL-g-P(GMA)2-c-gelatin. The successful immobilization of gelatin on the P(GMA) brushes can be deduced from the presence of a broad band of free O–H and N–H groups (at 3,295 cm−1), amide I band (at 1,642 cm−1) and amide II band (at 1,543 cm−1) as compared to the pure gelatin FTIR spectrum
