1-26. (canceled)
A method of screen printing on a substrate, the method comprising the acts of:
- providing a screen that includes a pattern defined by a first portion comprising a coating of a photosensitive emulsion, and a second portion lacking the coating of the photosensitive emulsion due to exposing the photosensitive emulsion;
- supplying a reagent on the screen, the reagent comprising a solvent, a cellulose polymer and an enzyme to assist in determining an analyte concentration of a fluid sample;
- and
- applying the reagent to the substrate via the second portion of the screen.
