Fig. 1. AFM height images (1 ¯ 1 µm 2 , contact mode, in water; z scale 10 nm) of native (nat),
silanized stainless steel (sil), the same after adsorption of glucose oxidase (sil+Gox) and after
treatment with glucose oxidase subsequent to treatment with the coupling agent
(sil+BS+Gox). Cross sections were taken at the place indicated by the dashed lines.
