31. For the OTS/air and OTS/buffer interfaces, one slab model did not produce acceptable fits, and the introduction of an additional slab was necessary to obtain reasonably good fits to the reflectivity data.
32. We also tried a two-slab model to fit the data for the Si/OTS/buffer interface by (i) taking the best-fit profile for the Si/OTS/air interface, (ii) replacing the air with the buffer, and (iii) allowing the parameters for the OTS-tail slab to vary freely; however, this approach did not produce an acceptable fit to the data.

38. If all the available lipid monomers are adsorbed on the hydrophobic substrate surface, the area per lipid molecule is A0 / (ρcmc ×0.8×6.02× 1023 /786.16) ∼1000′ 2, where A0 =72′ mm2, ρcmc ∼ 10-2 ′μg/ml, the volume of sample cell is 0.8 ml, and the molecular weight of DOPC is 786.16 g/mol. This molecular area value is much larger than that for a complete DOPC bilayer (80′ 2).
