Constructive Nanolithography and Nanochemistry: Local Probe Oxidation and Chemical Modification
-
Wouters, Daan; Schubert, Ulrich S.
- Abstract:
- The possibility to prepare and use submicrometer-sized patterns in successive functionalization reactions
with quaternary ammonium salts and (functional) chlorosilanes, as well as cationic gold nanoparticles,
is presented. Submicrometer-sized structures were prepared by local probe oxidation of octadecyl
trichlorosilane functionalized silicon wafers. By this method, patterns were oxidized with 40-nm resolution,
which can be used in local surface functionalization reactions. The principle of subsequent functionalization,
either with additional quaternaryammoniumsalts or by a polymer grafting reaction, has been demonstrated.
