A method for general linear response description of membrane adhesion at rough or chemically structured surfaces was presented. The adhesion was found to be less favourable for rough substrates. Chemical patterning described by a spatially varying Van der Waals force favored adhesion. The approach was found to be in good agreement with numerical solution while considering a surface indented with ″V″-shaped trenches.
