Modification of PLGA Nanofibrous Mats by Electron Beam Irradiation for Soft Tissue Regeneration

Figure 5

ATR-FTIR spectra for each e-beam irradiated (0–300 kGy) PLGA nanofiber mats after 2 weeks of incubation in PBS. Scan area of 4000–800 cm⁻¹ wavenumber range (a) and magnified spectra for identification of hydroxyl group ratio around 3600–3100 cm⁻¹ wavenumber range (b).
