Label-free surface-enhanced infrared spectro-electro-chemical analysis of the Redox potential shift of cytochrome c complexed with a cardiolipin-containing lipid membrane of varied composition

Liu Li, Wu Lie, Zeng Li, Jiang Xiu-E†

Surface-enhanced infrared adsorption (SEIRA) spectra of cytochrome c adsorbed onto the films CL_PC-DT(10) (curve a ), CL_PC-DT(20) (curve b ), or CL_PC-DT(40) (curve c ) at their individual time point of saturation adsorption. CL_PC: cardiolipin-phosphatidylcholine bilayer, DT: 1-dodecanethiol.
