Abstract:
A method for selecting a dye for determining authenticity of a product, comprising,combining a candidate dye with a plurality of candidate dilutions of a liquid sample of an authentic standard of the product, said candidate dye being light emissive at a particular wavelength when irradiated if it interacts with an analyte in the liquid sample, selecting a test dilution at which said candidate dye emits light at a selected intensity when said candidate dye is combined with said liquid sample at the test dilution, determining a range of intensity of light emission for a plurality of mixtures of said candidate dye and said liquid sample at said test dilution, determining an experimental intensity of light emission for a mixture of said candidate dye and a liquid sample of a nonauthentic product at said test dilution, and, comparing the experimental intensity to said range, said dye being selected as useful for determining authenticity of said product if said experimental intensity falls outside of said range.
