Abstract
The present disclosure relates to multilayer constructs for producing metabolite strips. The multilayer constructs include a substrate layer having a top surface and a bottom surface, a thin film metal conductor layer formed on the top surface of the substrate layer and configured to act as an electrode, and a Transparent Conductive Oxide (TCO) protective layer deposited on top of the metal conductor layer. The metabolic strips can be used, along with various measuring devices, for determining the presence of certain analytes in a specimen and for various like applications.
