Abstract:

Example paper substrate diagnostic apparatus and related methods and systems are disclosed herein. An example substrate-based diagnostic device includes a hydrophobic substrate, an electrode disposed on a surface of the hydrophobic substrate, a layer of reagent disposed on or near the electrode, and a layer of hydrophilic ink disposed over the electrode and the layer of reagent. The hydrophilic ink is to wick a sample to the layer of reagent.
