Surface adsorption models of cyt c according to our results on surface-enhanced infrared adsorption (SEIRA) differences and previously reported results.^{[ 16 , 18 ]} Left panel: Cyt c adsorbed on the MUA-gold surface with high polarizability. Right panel: Cyt c adsorbed on the CL_PC-DT-gold surface with low polarizability. CL_PC: cardiolipin-phosphatidylcholine bilayer, DT: 1-dodecanethiol, MUA: 11-mercaptoundecanoic acid.
