1. A method for identifying the presence of a target molecule or ion, comprising:
transferring a molecule or ion from a surface to a first chemical reagent applied to a solid support; and
allowing the chemical reagent to react with the transferred molecule or ion, whereby a presumptive color indication is produced that identifies or excludes the presence of the transferred molecule or ion as a first target molecule or ions;
wherein the first chemical reagent comprises a micronized powder that is mixed with a dispersant to reduce the viscosity of the micronized powder to form a temporary flowable liquid applied to the solid support and thereafter dried such that the dispersant is removed.
