Abstract

A novel approach to the use and fabrication of disposable electrochemical sensors has been detailed. Carbon fibre foils were sandwiched between an insulating polymer with multiple, individually addressable layers built up to form the basis of a three electrode sensor. Coring the laminate revealed a microtube electrode configuration within a ``detection well'' with sample volume defined by the filling of the void. The modification of the base fibre mat with copper oxide was found to produce a microstructured deposit through which the sample permeates and selectively removes ascorbate. The mechanical integrity of the construction has been assessed by electron microscopy and the electrochemical characteristics investigated using the oxidation of urate as a model analyte.
