(1pt tоtаl) A reseаrch grоup recently published аn article where interested in mоdified the surface of polymer to promote cell adhesion. This specific polymer base was poly(l-lactide-co-ε-caprolactone) (PLCL) that is notorious for having limited functional groups available to facilitate surface modifications. Yet, the group knew the needed to covalently immobilize a protein to the surface to support cellular adhesion. (0.25pts) The group employed a combination of gamma-irradiation grafting of an acrylic acid group to facilitate a covalent reaction with the protein, gelatin (see schematic in part B for details). Briefly describe radiation grafting. (0.5pts) The schematic above outlines the various phases of the surface modification, starting from the native PLCL film to after radiation grafting in the presence of acrylic acid (AAc) to the chemical reaction performed to covalently immobilize gelatin on the surface. The researchers used electron spectroscopy for chemical analysis (ESCA) to confirm surface modification. Match each ESCA spectra with the corresponding point in the grafting process: native PLCL, AAc grafted PLCL, or gelatin-PLCL. The chemical structure of PLCL is provided below. (0.25pts) The researchers would like to characterize the approximate amount of gelatin that is immobilized on the PLCL surface. Name AND BRIEFLY describe one method to detect the amount of gelatin on the surface of the PLCL.
