Selective adsorption of human serum albumin and human γ globulin to the liquidlike phase of chemically homogeneous, mixed phospholipid monolayers supported on a solid surface gives rise to arrays of linear 150–200-nm-wide grooves (see images). The protein-covered areas could be metallized by the adsorption of Au nanoparticles.
