FTIR spectra of DOPC-MPE sample. (a) The FTIR spectrum of DOPC-MPE vesicles before (black) and after (red) irradiation. A small blue circle indicates a characteristic lipid peak used for normalization. Lilac and green areas are enlarged below to present the characteristic spectral changes: the increased νas(C = O) peak (b), and the shifted and increased νas(PO2−) peak (c).
