(0.5pt tоtаl) Pоly(cаprоlаctone) (PCL) is a bioresorbable polymer that is used in a number of biomedical applications. A research team aimed to improve the cellular interactions by covalently grafting an adhesive protein on the surface of PCL films via acrylic acid (AAc). Below is an FTIR assessment of the chemical modification process, (a) = native PCL, (b) PCL-AAc film, (c) PCL-protein. For PCL, the major absorption peak is observed at 1730 cm-1 due to the COO functional group. The researchers note the emergence of an absorption peak in the PCL-protein group at 1566 cm-1, but did not cite the corresponding functional group. (0.25pts) What additional information would you need as a reviewer of this FT-IR data set to have confidence in the conclusion that the protein is covalently grafted to the PCL film? (0.25pts) What additional characterization assay discussed in Unit 1 would further confirm chemical modifications the native PCL film?
