MATERIALS AND METHODS FOR THE QUANTIFICATION OF A FLUID
A composition for application to a substrate to form a film or deposit for quantifying a fluid, or one or more analytes within a fluid, is disclosed. The composition includes a carrier configured as a transport medium for application of the composition to a substrate and at least one salt of chloranilic acid. The carrier can include at least one compound soluble within a bodily fluid and configured to at least partially solidify upon application of the composition on the substrate. The carrier can optionally include a liquid medium as a bulk transport medium for application of the composition. In some aspects, the liquid medium can be water, the at least one compound can be one or more water-soluble polymers, and the salt of chloranilic acid can be silver chloranilate. A color change in response to the film or deposit dissolving in the fluid and the at least one salt of chloranilic acid reacting with the one or more analytes allows for the quantification of the one or more analytes, and/or a quantification of the volume and/or flow rate of the fluid.
1 . A composition comprising:
a carrier configured as a transport medium for application of the composition to a substrate; and
at least one salt of chloranilic acid contained within the carrier.
2 . The composition of claim 1 , wherein the at least one salt of chloranilic acid is silver chloranilate.
3 . The composition of claim 1 , wherein the carrier comprises a liquid medium of water, an alcohol, an oil, a volatile organic compound, or a combination thereof.
4 . (canceled)
5 . (canceled)
6 . The composition of claim 3 , wherein the carrier comprises at least one compound soluble within a bodily fluid and configured to at least partially solidify upon loss of the liquid medium after application of the composition on the substrate.
7 . The composition of claim 6 , wherein the at least one compound includes at least one polymer of polyethylene glycol, polyvinylpyrrolidone, polyvinyl alcohol, or a combination thereof.
8 - 18 . (canceled)
19 . A composition soluble in a bodily fluid comprising:
