モレキュラーインプリント法により作製した自己組織化膜電極を用いるビタミンK₁の認識

抄録

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 K₁ and K₃.The monolayer film showed a voltammetric response only to hydrophobic vitamin K₁ molecules, while a film without the hexadecane template showed neither a peak assigned to vitamin K₁ nor K₃.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.
