Neutron reflection has been deployed to study the adsorption of short designed peptides and proteins at the solid/water interface, focusing on the determination of the structure of the interfacial layer. The effects of surface hydrophobicity, the size and stability of globular proteins and the solution environmental conditions on the structure and composition of the adsorbed protein layers are examined and key features highlighted. The advantegeous features of neutron reflection are described.
