Resume : Frontier research in surface and biological sciences engage with a deeper understanding of mechanism associated with protein-surface interaction. To control molecular adsorption onto a surface one would consider altering surface properties. As a distinctive approach, we have elucidated the contribution of subsurface layers; the region buried several nanometres below the surface, to the protein adsorption via generating long-range interaction forces. Highly crosslinked, nanoporous subsurface vertical chemical gradient layers were designed by plasma polymerization. Based on hexamethyldisiloxane (HMDSO), the vertical gradient structure consists of a relatively thin, hydrophobic plasma polymerized HMDSO terminating layer on a thicker, hydrophilic plasma polymerized SiOx base. Moreover, an enhanced gradient was generated via post-oxidizing the base layer r
