Fourier Transformed Infrared spectroscopy output of the PCL nanofiber scaffold. (a) The repeating monomer that makes up poly(ϵ-caprolactone). (b) FTIR iD1 transmission output of a scanned pure PCL scaffold. Peaks of particular interest are highlighted. (c) Output of a scanned PCL scaffold coated with thymosin B4. Notice highlighted differences where proteinaceous material stands out from the pure PCL graph.
