abstract = {Modifying the surfaces of oxides using self-assembled
monolayers offers an exciting possibility to tailor their
surface properties for various applications ranging from
organic electronics to bioelectronics applications. The
simultaneous use of different molecules in particular can
extend this approach because the surface properties can be
tuned via the ratio of the chosen molecules. This requires
the composition and quality of the monolayers to be
controlled on an organic level, that is, on the nanoscale.
In this paper, we present a method of modifying the surface
and surface properties of silicon oxide by growing
self-assembled monolayers comprising various compositions of
two different molecules, (3-aminopropyl)-triethoxysilane and
(3-glycidyloxypropyl)-trimethoxysilane, by means of in situ
controlled gas-phase deposition. The properties of the
resulting mixed molecular monolayers (e.g., effective
thickness, hydrophobicity, and surface potential) exhibit a
perfect linear dependence on the composition of the
molecular layer. Finally, coating the mixed layer with
poly(l-lysine) proves that the density of proteins can be
controlled by the composition as well. This indicates that
the method might be an ideal way to optimize inorganic
surfaces for bioelectronics applications.},
