Abstract: In this paper, we present a novel way to design a self- assembled monolayer, based on molecular imprinting protocols, for the selective recognition of hydrophobic molecules. A monolayer of octadecanethiol, templated with n-hexadecane, was fabricated on a gold substrate, and its voltammetric behavior was examined with vitamin K-1 and K-3. The monolayer film showed a voltammetric response only to hydrophobic vitamin K-1 molecules, while a film without the hexadecane template showed neither a peak assigned to vitamin K-1 nor K-3. The results demonstrate that the present technique can be used as a simple and highly selective surface-designing tool for the fabrication of a self-assembled monolayer based electrode
Template and target information: vitamin K1
