G. Fragneto et al., Neutron and X-Ray reflectivity studies at solid-liquid interfaces: the interaction of a peptide with model membranes, PHYSICA B, 276, 2000, pp. 501-502
A neutron reflectivity structural study of model biological membranes in th
e gel phase interacting with a 16 amino-acid peptide is presented. Membrane
s were prepared with the Langmuir-Schaeffer technique and measurements were
done at the solid/liquid interface. Details of the structure at the interf
ace were obtained at 1 Angstrom resolution. While with neutral lipids no sp
ecific interaction is detected, in presence of negative charges in the memb
rane the peptide interacts mainly with the lipid headgroups. The complement
arity of neutron and synchrotron radiation measurements is mentioned. (C) 2
