Abstract
Example paper substrate diagnostic apparatus and related methods and systems are disclosed herein. An example apparatus includes a hydrophobic substrate having a first end and a second end opposite the first end. The apparatus includes a detection zone on a first surface of the substrate, the detection zone defining an area to sense an analyte in a sample, the detection zone comprising a first electrode and a second electrode disposed on the first surface of the substrate and a layer of hydrophilic ink disposed on the two electrodes and an area between the first and second electrodes. The apparatus also includes a channel comprising hydrophilic ink disposed on the first surface of the substrate, the channel having an inlet section adjacent the first end of the substrate, a middle section, and an outlet section in contact with the layer of hydrophilic ink. The channel is to transfer a fluid sample from the inlet section to the layer of hydrophilic ink.
