1. A multilayer construct comprising:
- 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, wherein the conductor layer is formed from a metal alloy that is a nickel-based alloy, a cobalt-based alloy, an indium-based alloy or a tin-based alloy and wherein the metal alloy further includes aluminum, niobium, titanium, tantalum, rhenium, hafnium, boron, yttrium, chromium, molybdenum, cobalt, ruthenium, tungsten, vanadium, platinum (Pt), palladium (Pd), rhodium (Rh), iridium (Ir), or osmium (Os); and
a protective layer deposited on a top surface of the conductor layer, wherein the protective layer is formed from an oxidized Transparent Conducting Oxide (TCO).

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.
