Neutron scattering-length density (nSLD) profiles, ρb(z), calculated for the VSD:POPC membrane tethered to the surface of a SiNiSi multilayer substrate (upper left) and for the SAM chemisorbed onto the surface of a SiNiSi multilayer substrate (upper right), each at a transmembrane potential of 0 mV. The aqueous buffered KCl electrolyte was in 90% D2O:10% H2O. The respective difference nSLD profiles, Δρb(z), for each case are shown in the panels below for the pairs of potentials indicated. The nSLD profiles are in units of 10–6/ Å2.
