Abstract

A method is provided for constructing a platform for use in a sensor in a microfluidic device. The method may include the steps of selecting a polymeric film, laser drilling at least one frustoconical pore in the film, depositing a layer of metal suitable for use as an electrode over a wall of the pore, and depositing a membrane capable of detecting an analyte in the pore over the metal layer. The method may also include the additional step of forming a diffusion limiting layer in the pore at an exit end of the pore before depositing the membrane capable of detecting an analyte.
